Help 4 DHCP Cable modem on Vlan SF 300-8

I have Multiwan router with 1 port WAN and 4 DHCP Cable modem connected to SF 300-8. I want to connect 4 modem via VLAN through switch. I define Vlan2,3,4,5 on router also in Switch. port 1 on the router as trunk and the other port 2,3,4,5 as Vlan2,3,4,5 with VLAN mode Access. I tag port 1 on every VLAN also Untagged for each port. I having problem when I check the status from multiwan router. all IP address is the same (duplicate). what I want is each VLAN has own DHCP Address. Is that any miss configuration ?
Your help is really appreciate.
Thank you

I do not have first hand experience with the Q Balancer but it should not be behind the switch as shown in your diagram. The Q-Balancer is a router and technically so are the modems, so by placing the switch in between you are defeating the purpose of the balancer. I may be completely wrong...
The other thing is that you are trying to IP the modems but you are not routing anything. This will be a very long response and what I will try to do is create a Visio showing how it should be laid out. The basics is that the connection between the Qbalancer and the switch should be Point-to-point with a route statement for all your subnets. The switch should be a L3 switch with DHCP relay enabled and pointing to your DHCP server (Qbalancer?). But the thing is that now we create a problem, how is the traffic coming in from the cloud. I mean is the destination a single subnet behind the QBal. or what?
I just do not understand why you would have the switch between the Modems and the Qbal.? Where is your LAN? Are you provisioning the modems like an ISP? Are you providing a service or is the internet service being provided to you?

  • Need help switching from cable modem to DSL

    Howdy all. I've had an iMac for a few months now and I'm still clueless. LOL (PC user for years). Please list all the steps I need to do to switch from dial up to DSL. All help is appreciated and needed.
    Thanks.

    As you dont say where in the world you are it is impossible to give specific information. However this is how it works in the UK. ISP's dont install anything for you. You sign up with the ISP, you purchase a package, this varies from the speed i.e 2mb, 8mb 16mb 20mb per sec.
    You then have options such as unlimited downloads, or a monthly data cap. Then you pay for your first month usually with a debit/credit card and setup a direct debit from your bank account there after. Some contracts are for 12 months others are 3 months and some are 1 month at a time.
    But the thing you need to be aware of in the UK if you already have cable then this usually means you have cable TV and a cable provided phone line. In the UK you cannot get DSL on a cable phone line you have to get a British Telecom line.
    You then provide your BT phone number to the ISP. Then after they process your payment they inform you as to when your line will be activated and then they send you a preconfigured ADSL router. You just then follow the instruction plug it in and it works. Most boxes have WPA setup already and have the password printed on the bottom of the router. An engineer does not come to your house unless the is a problem and they detected a line fault that requires and engineer visit.
    Of course if you are a business you can pay for a engineer visit to setup the network as well but this costs money.

  • 10.5.6 setup on mini with USB nic, not receiving DHCP from WAN (cable modem

    Hello,
    I'm probably in a little over my head thinking I could configure MacOS X Server without much IT knowledge. But I started, so I'm not giving up yet.
    Here's my setup:
    — cable modem ethernet connects to USB nic (the apple macbook air one) plugged into mac mini running 10.5.6 Server
    — ethernet on mac mini connects to switch
    — switch connects to airport base station set-up as bridge
    — in the future other computers will connect over ethernet to the switch (that's why mac mini isn't plugged into base station directly)
    Here's the issue:
    — cable modem uses DHCP (no fixed IP).
    — when first installing 10.5.6 Server, modem was connected directly to ethernet on mac mini, and picked up everything from DHCP, worked fine. Ran all the system updates (started with a 10.5 initial install)
    — after everything was installed, I switched the modem to the USB ethernet adapter and ran NAT setup assistant. configured the USB Ethernet as the WAN, Ethernet as the LAN, turned on VPN.
    — now the USB Ethernet won't pick up the DHCP of the WAN anymore. It did it once, and then never again.
    — I've run the NAT setup assistant to switch the WAN and LAN nics to see if the USB Ethernet was the issue, but with the same results.
    — This setup used to work although not quite stable on 10.5.4 server.
    My initial questions:
    — is the firewall blocking the DHCP?
    — is the LAN DHCP messing with the WAN?
    — in the previous version I had to set the replythresholdseconds from 10 to 0 in the bootpd.plist for it to hand out DHCP on the LAN, but there is no such entry in the pootpd.plist anylonger, and the keynet_address entry that was missing from the previous version of bootpd.plist is now present, so it seems the bootpd.plist has been fixed by apple.
    — what am I doing wrong? Why doesn't this just work as advertised...
    I know there are several of you out there that have the same setup working (I found posts from hirstey and DigiAngel with the same setup) so it must be possible. All your help is much appreciated!!
    Thanks,

    Thanks for your reply, DigiAngel.
    DSL modems differ from cable modems as far as I understand. Where DSL modems are actually routers capable of NAT/DHCP, cable modems are just a network interface/brigde and can't do any of that. So it should pass the external IP to the computer. I'm writing on a laptop with the cable modem directly plugged into it, and it picked up the external IP etc. near instantly. The mac mini did the same before I ran the NAT setup assistant. I believe it picked it up once after that, but never since.
    I had done a clean install, had the ethernet plugged into its internal ethernet port (en0) and was able to download all the system updates. Then plugged in the USB ethernet, I'm pretty sure it still picked up the IP there. Ran the NAT setup assistant and can't get anything to work anymore. Even with all services switched off.
    So the modem is doing its job, but when I connect it to the USB nic the connection gets a self-assigned IP in about 3 seconds after seeing the cable is connected. The one time I've seen it get the right IP, it got a self-assigned IP first and then about 5 seconds later picked up on the correct IP. (And it picked up everything, including DNS server and search domains, which this laptop I'm writing on does not, although it works just the same).
    Unfortunately, this laptop runs 10.4.11 which doesn't recognize the USB nic, so I can't test the adapter outside of the server environment. But I've had the genius bar test the adapter previously and it worked fine then, plus I've run the NAT setup assistant with the connections inverted (WAN over built-in ethernet, LAN over USB ethernet) with the same results: WAN gets self-assigned IP.
    I've also tried configuring manual IP for the WAN from what I saw was given to this laptop (it kept the same IP even after being disconnected/reconnected, so I guess the IP for my modem won't change IP unless I reset it. Although I'm not sure if it's correct logic to assume the mac mini would pick up the same IP as well since I think that's actually tied to the MAC address and the IP doesn't belong to the modem but to the computer behind it).
    Anyway, I'm not sure what to try next...
    Hm. Wait, this might have something to do with it: the firewall logs the following:
    Mar 22 14:12:07 server ipfw[4997]: 65534 Deny UDP 73.227.220.1:67 255.255.255.255:68 in via en 2
    Looking up 73.227.220.1 gives me dns1.inflow.pa.bo.comcast.net, clearly my provider's DNS server. Trying to get me an IP that my wirewall is denying? Turning off the firewall doesn't make it pick up the correct IP though... I have turned off all services and still just got a self-assigned IP.

  • WRT54GS slamming Cable modem with Packets

    I'm having trouble with my WRT54GS locking up my Cable Modem. TWC says its slamming the cable modem with too many packets. Is there any way to check this on my end? Full story below.
    A little about my set up. I have Time Warner Cable business class Roadrunner service. 5 Static IPs. 4 being used at the moment. The Cable modem has a 4 port switch built in. Port 1 has a month or so old WRT54GS router v7 latest firmware (Gateway mode, Channel 6). Port 2 goes to my Sonicwall Barracuda them my internal network which also has WRT54GS router v7 latest firmware (Router mode, Channel 1). Both routers are sitting next to each other. Ports 3 & 4 have a Vonage Router hooked to each of them.
    I started having trouble April 5 with the Internet being down that morning, then that night and falling morning. I power cycled the Cable modem to restore service. Called Time Warner Cable after the third reset. They told me that didn't see anything wrong from their end and I should call them when it is down. I did this and they said they would send someone out the next morning Friday. They came out on Friday morning and Checked cable which the tech said was fine so he replaced the Cable modem around 11:30. Fifteen minutes after he left the internet went down. I called TWC again. They did diagnostics on the cable modem from their end and saw that whatever was hooked up to port 1 was sent out 400 packets/sec. I think they said the cable modem could only handle 300. Port 1 is connect a WRT54GS v7 (latest firmware). We are using it for our Blackberries from Cincinnati Bell for WIFI and UMA service (like T-Mobiles @Home service) for VoWiFi. I turned off all the phones but the router was still slamming the modem with packets. I turned off the WiFi just in case someone hacked our WPA2 key. Still slamming the router with packets with only my laptop hardwired to it for setting up the router. I turned off the router and the modem wasn't getting hammered anymore. Port 2 which is my internal network was only up to 150 after open a lot of TV shows. Ports 3 & 4 nothing. I disconnected the WRT54GS hooked to Port 1.
    15 minutes after I got off the phone with TWC internet goes down. They send out a tech on Saturday to check the line again. he sees a slight problem on the line but it should not be causing a problem which the first guy might have thought. But since I am having trouble he goes outside and checks the connections. He finds loose connection and a bad line cap (blocking cable TV). He fixes the connections and replaced the line cap. He comes back inside and rechecks the line. Everything is great no more fluxation of signal or packet loss. I hook the WRT54GS back but it still takes down the modem. So I figure that it's just bad. So I take the WRT54GS from my internal network and set it up to match the one for the Blackberries it's replace. I install a WAP54G on the internal network in it's place. I can't get my Blackberry to get a UMA connection and doing Google searched find this page
    http://www.blackberryfaq.com/wiki/index.php/Linksys_Router_Tips
    I set up my router and Assess point with the setting from the above except the channel setting leaving them on channel 6 & 1 so they don't interfere with each other. Set: Fragment Threshold : 2304 (256-2346), RTS Threshold : 2304 (0-2347) and Beacon Interval : 50 (20-1024 ms). I also Enable WMM QOS. My phone connects and internet seems to be staying up Saturday Evening. I come to work Sunday afternoon and Internet is still up. I check my phone I have UMA signal and everything is right with the world. 20 minutes later internet goes down. I unplug the WRT54GS and power cycle the cable modem. I am now waiting to see it the internet will stay up without any WRT54GS hooked up.
    I have not had a problem before and both Linksys are not even 6 months old. I have read review were people have had trouble with the WRT54GS. Were some people have no trouble will other all kinds of trouble.

    As you said cable connected to the pc is working fine!!...connect modem to the router WRT54GS...reset the router once (30 secs) in such a way that Power light on the router is blinking...power cycle complete network i.e., unplug modem & router power cable for 30 secs...plug in modem power cable once lights are solid green plug in the power cable to the router...its important that after upgrading firmware resetting the router is important...so try this & it should deifnately work.Do the wireless & advanced wireless settings as router is currently in default settings.
    Also, you want to connect your access point WAP54G to the router & open the setup page of WAP54G using 192.168.1.245 do the wireless settings & try connecting to the wireless router & then check....should work.

  • Router connected to cable modem by Ethernet port cannot get IP address from DHCP.

    I have an ethernet cable on Fa0/0 connecting my 1841 router to my cable modem. The issue is that the router cannot obtain an IP address via DHCP when I have the "ACL-OUTSIDE-IN" ACL applied inbound on the Fa0/0 interface. I tried to allow all BOOTP and BOOTPS traffic in my ACL, but still no luck. I really don't want to run the router without a simple ACL firewall and connect it to the internet. When I take off the ACL off of Fa0/0, the router is able to get an IP address via DHCP.

  • Setup 1941 router with cable modem and 2 vlan?

    hello everyone,
    i need a little help setting up my new 1941 router with cable modem using 2 vlns.
    this is what i have:
    1- 1941 router configured as g0/0 wan port facing isp configured as (dhcp). g0/1 is lan facing the switch (192.168.1.1)
    dhcp pool (192.168.1.x)
    2- sg300-28pp switch.
    3- wap371 AP/ 11pcs..
    now everything is working perfect except sometimes we have more than 250 to 300 people trying to connect to the wifi, the router will have no enough ip addresses.
    i heard that i can setup 2 vlans to solve this problem? and is there any setup that i have to do on switch and Access points? 
    please i will appreciate any little help 
    Regards 

    hello Andre Neethling  i added network 192.168.0.0 255.255.254.0 to dhcp pool config and it seems that it is working but i am concern that i am going to have problem in the future so please take a look at the running config and let me know if i have everything done right. also we want to order static ip address from the provider for our security camera system and we will not longer receive dhcp ip from them and my router setup is to receive it as dhcp on g0/0 so what i should do about changing the settings on g0/0?
    i appreciate your help

  • Hi, I have a MacBook Pro and a PC both connected to a TC who in turn is connected to a cable modem. I have no wifi accessfrom my MacBook pro (self assigned IP - no internet connection msg) while I do on PC through ethernet? can anyone help?

    I was working yesterday afternoon when the wifi suddenly went cold. Initially on the MacBookPro and on the ethernet connected PC. I reinitialized modem and TC  through the mac and then the ethernet on the PC worked again and has since. 
    I've reinitialized both the modem and TC many times, as well as checked the cables. Moreover, I've tried to renew the DHCP lease, provide the DNS servers manually, erased all networks in Network preferences and in KeyChain etc. but nothing seems to work.
    One strange thing also happened. I had two networks created, one for me and one I created for guests. The latter one just vanished, dissapeared without a trace.
    I've tried from the café down the street and the Wifi worked perfectly well though a little slow, but that could be their connection not the Airport. Therefore, my  I deduct that there is either something wrong in the TC or something went wrong in the network settings in the Mac. But that doesn't help to move forward and fix the darn thing.
    The only thing I haven't done is completely reset the TC, but after reading a couple of help threads on different forums I'm confused as to how to proceed to get it back to worrk? Has anyone had the same or similar issue and found a solution?
    Thanks

    Eh la Pastenague! Je savais que tu était léthale pour l'homme mais ce sont pluôt les machines à pommes qui devraient te craindre. Merci! Solved. 
    For future reference.
    My TC is a 3rd gen.
    I actually had to reset to standard defaults not only once but twice. The first time I simply returned to my old profile but that only led to the same message error on the network settings (i.e. IP by default, cannot connect to the internet). Therefore the second time around I kept my profile as backup and re-created a new one plus a guest one.
    The airport utility then signaled to issues remaining:
    1) Internet access was cut - this I solved by simply reseting the cable modem
    2) There were no DNS Servers - I simply copied the ones I had from the previous setup and it worked
    I did have AppleCare....
    I'm online again and I hope for good.
    Thanks a lot
    PS. a small tip - I made captures of all my settings in Network settings, Airport Utility and Network utility using Grab in case of ... if anything it is just handy to get back settings that your are missing when setting up a new configuration

  • EA4500 Won't get a DHCP WAN address from Cable Modem

    I have an EA 4500 that I used to replace a bad WRT45 (or something like that).  We have an ADT camera system that allows you to view the cameras locally and remotely.  All I have to do is set a static internal address on the DVR and the public IP on the router in the application.  I duplicated the setting in the old router and everything was running smoothly.  However, the speed test result I was getting from the router and speedtest.net were not even close to what we were paying for (wireless and wired.  But it was functional. 
    I called Comcast and they said we needed a Docsis 3 modem.  So, I went to the Comcast office and they traded out my modem for a docsis 3.  Hooked it up and everything was working again.  Speeds were better but not really up to par.  Hooked my laptop directly into the new modem and I was getting speeds off the charts.  Frustrated, I called Comcast, they said the modem needed to be put in Bridge mode. Then the EA4500 wouldn't get a DHCP WAN adress.  They took it out of bridge mode.  Same result. 
    They sent a tech out (Mind you I've been a Network Engineer for almost 20 yrs) and he tells me they gave me the wrong modem (I wasn't there either, roommate let him in).  He replaced the modem with a new all inclusive router/switch/wifi modem.  He then proceeds to setup a whole new network, which of course , except the laptops that connected, my devices don't see ( printers, cameras, dvr, etc).  Then, this baffles me... he did a factory reset on my EA4500. So now there are 2 seperate networks one with slow Internet and one without WAAN services. 
    After all this, my EA4500 still will not get a WAN address when plugged into the new modem.  I would just use their new modem but to make any config changesto it, something as simple as changing the SSID name or the password, you have to call them.  They won't give you access to the admin page.
    Anyone have any ideas why my EA4500 won't get a WAN address? Oh, btw, I did do a MAC address clone on the EA4500 while connected to the modem and it DID get the address, but the speeds were dismal, not even 1mb up or down.

    @stix180
    There is a need to reset and reconfigure the EA4500 router to work with the new modem. There are certain configurations on the router that will make it work for a particular modem, and this might be causing the issue. Cable modem authenticates end users through username and password but there are cable modem/router as well in which the IP address are on the same range with the default IP address of the router. Please try to check the IP address of the computer wired directly to your modem, it should not be on the same IP address range with the EA4500 router since it will cause IP address conflict. You can change the default IP address of your router from 192.168.1.1 to 10.10.10.1. Please try to make sure that your router also has the latest firmware version installed. And it would help if you do port forwarding on the router for your camera and DVRs to resolve NAT issues.

  • Unable to DHCP from Cable Modem

    I have to manually set the external ip on my TC every time my ISP (Knology) updates my cable modem. If I set the TC to receive DHCP from the modem, I don't receive an IP. I've reset my modem many times using a variety of methods. Nothing helped. As soon as I connect my MBP directly to the Modem and receive the latest public IP, I turn right around and enter the IP into the TC. Knology provides a renewed public IP on the average of once a week. Obviously having to reset the TC once a week is time consuming and annoying. Any ideas?

    What other ISPs are available? Perhaps it is time for a change to an ISP which is more user friendly.

  • No DHCP, I just want the cable modem address

    I've been trying to setup my airport without any DHCP stuff whatsoever. I just want the airport express to echo the same IP as if I were to plug my cable modem directly into my computer. I realize this limits me to only one computer at a time on the airport, but that's exactly what I'd like.
    Thanks for the help in advance.

    Hello dkuhlmann. Welcome to the Apple Discussions!
    You just need to set up your AirPort Express Base Station (AX) as a bridge...
    To set up the AirPort Express Base Station (AX) as a bridge, either connect to the AX's wireless network or temporarily connect your computer directly (using an Ethernet cable) to the Ethernet port of the AX, and then, using the AirPort Admin Utility (located in the \Applications\Utilities folder), make these settings:
    Network tab
    - Distribute IP addresses (unchecked)
    - Apply the new setting.

  • I need help setting up a wireless network and getting connected to the internet. I have a RCN cable modem now and tried to install a wireless linksys today and it was a disaster

    I have a MAC desktop and RCN cable that I have internet through now. I tried to set up a linksys wireless router today and could not get the network settings right, or figure out how to create the network, or get connected. I was successfull for only a few minutes because my phone and laptop had picked up the signal. However my desktop still would not connect to the internet. I had to restart my cable modem after because even after returning to directly inserting the desktop to the modem I could not get on the internet. I am able to get on now but would like to have wireless for my laptop and phone. Do I have to have an Apple router? Are there any easy steps I can take to set up a network without doing any damage to my desktop? I am so lost and have been getting pop ups and even my time changed.
    Please help a new person to Apple!

    why dont you go to linksys.com/downloads and get the quick install for your adpter

  • My 3000H will no longer connect to the internet via my cable modem - help please.

    I have 3 computers and a media server on a Linksys router with a Comcast cable modem. Everything AOK. 3 weeks ago my Lenovo 3000H shut down and rebooted for no reason. Then I began getting popups while I was on the internet saying that I needed to click on a button to make a dial-up connection. I would hit X or Cancel to make it go away. It happend more frequently and other related popups started, but I could close them and continue normally. Last weekend It happened again but I lost my connection to the internet and it would not reconnect. Now I get a big error message "Connecting through Wan Miniport(PPPOE)... Error 815: The broadband netowrk connection could not be established on your computer because the remote server is not responding. This could be caused by and invalid value for the "Service Name" field for this connection. Please contact your ISP and inquire about the correct value for this field and update it in the Connection Properties..
    I called Comcast. They don't have a clue what Error 815 is. I have changed every cable, rebooted the modem, router and all computers countless times, and reset the modem per Comcast. I have taken the router out and connected directly into the Lenovo. I have gone through every screen related to broadband connection to no avail although, being a beginner, I see screens that I have no clue what they do.I have a couple of friends and a Comcast fellow who tried to walk me through the steps they thought would restore my connectio. No luck.
    Can anyone walk me through the necessary steps to get me back to ground zero and then through the steps to reestablish my broadband connection?
    Help Please?

    Emma-
    In Safari, press on the Bookmarks icon and select History.  Then press on Clear History at the top of that menu, and see it there is any improvement.
    If not, try unplugging your WiFi router for a few seconds.  Then reset the iPad's network.  Go to Settings-General-Reset-Reset Network Settings.  You will need to reconnect the iPad to WiFi.

  • NTL/Virgin Cable Modem trouble... Need help please...

    Hello,
    I am a new NTL user, meaning I got the confirmation letter from NTL and then when they came to install it, the entire package turned into Virgin. They promised me a 10mb line which they say I have and a week into my TV and broadband cable modem experience, they dropped the Sky Channels. I wasn't too happy about that. But I wouldn't mind so much if only my internet was as stable as they said it would be.
    I am new to Cable Modems and I have always had ADSL, which I think is much more stable compared to my cable modem.
    I have a supposed 10MB line and a little blue box with a strange thick wire going into it and an ethernet cable going out of it into my new Airport Extreme (Flat one).
    My problem is this, aside from the fact that I constantly have drop outs and sometimes complete loss of signal, the Airport is in a fixed place no more than 3 meters from my MacMini Core Duo.
    I also don't think I have a steady 10MB line, cause when I try to download files from Apple or their trailers, it is VERY slow. I came from a 4MB ADSL and it was REALY FAST! So why is Cable slower?
    Am I doing something wrong here? The entire set up from Virgin was more or less non existent and they didn't help much on the phone.
    How can I have a more stable line and get at least 4 MBs out of the 10MBs they claim I have....
    It jumps high during a download and a few seconds later it drops to the point it simply isn't worth it...
    I would appreciate any info you could give.

    PS. the NTL Modem is called NTL 250 that is all it is a tiny blue modem of sorts...
    I am on a MacMini Core Duo which version of Airport card is in it I don't know and don't even know where to look for the info on it. But All I do know is that I often experience drops in my signal and sometimes a total loss of connection...
    Thanks

    Hi.
    I've been a Telewest - now also Virgin Media customer for many years, and have been using their 10mb connection for over a year now ( are you aware that in May they're upping it to 20mb)
    The speed of the connection is quite erratic, but for me has improved since xmas.
    Here is a site that will check your speed, if you still have problems, call them up, and even though they're not very Mac friendly, insist that they come round and check it.
    http://www.thinkbroadband.com/speedtest.html
    By the way, I called them when they lost Sky, and threatened to leave - they gave me a 20 quid/month discount - give it a go!

  • Multiple sites ASA's connected to Cable modems with same DHCP address

    I have several locations with an ASA 5505 installed behind a cable modem. The cable modem is issuing DHCP for the same network address range in these locations. I have the outside interface obtaining DHCP from the cable moden network and the asa's are receiving the same outside address. I have the remotes set to use EZVPN to create the VPN tunnel back to the head end ASA 5540. I am seeing constant rekeying for phase 2 for those remote sites. is there any thing I can do short of assigning each asa a unique outside address?

    Dave
    The Linksys doing NAT is the reason why the ASA sees all the traffic as having source address as 192.168.2.1. The only way for the ASA to see the original 192.168.1.x address is to change the Linksys to not do NAT.
    One thing that I notice is that there is not a route statement in what you posted for the 192.168.1.0 network. It is not clear whether the route does exist and you did not post it or whether the route does not exist. But if it does not exist it would certainly be a reason why you lose Internet connectivity when you change the Linksys to not perform NAT. (the ASA would have no knowledge of how to forward to the network and would drop all the traffic). Try adding the route to the ASA and changing the Linksys to not perform NAT and let us know if it works.
