RV215w PPTP with 192.168.1.x subnet

I have been trying to setup a PPTP VPN with the Cisco RV215w router and have discovered that CISCO won't permit a 192.168.1.x network when a PPTP VPN is setup. I am well aware that I can't have an identical subnet at the other end, and have made accommodations for that. The copy machine people have installed some equipment and I don't have access to those machines to change the subnet on them. Hopefully there is a work around for this!

Hello,
Are you on the latest firmware (1.2.0.15)? If not, you are most likely running into bug (CSCuh20473).
This bug does not allow you to add a zero to the local subnet.
I hope this helps.
Regards,
Chris

SA 520W VPN problem with 192.168.1.x (WARNING: In order to ensure proper functionality, the router will ...)

I need help. I can find no documentation on this problem. I have a Microsoft Small Business Server which I have been running for some time. I have been using for the last 10 years the private IP space 192.168.1.x, with subnet mask 255.255.255.0. I have an Active Directory structure that is based on this address space with my default route for the network at 192.168.1.254. I recently purchase a CISCO SA 520W appliance. Every time I add a VPN user to the VPN User Database, I get a popup that states "WARNING: In order to ensure proper functionality, the router will need to change its IP address to 10.x.y.1 to avoid conflicts with the remote network. You will need to reboot all PCs and network devices connected to the router. If you have set static IP addresses on any device or if you are using port forwarding, you will need to update its IP address to new IP range to operation. Would you like to continue?" With a se;ection of "OK" or "Cancel". If I select "OK" the router resets and I can no longer get access to it, resulting in me setting it back to factory default and starting over.If I select "Cancel" at this point it does not add the user to the database. I have tried everything I can think of. If I use the default IP address or any other IP address space, as long as I don't use 192.168.1.x, it works fine. This seems to be some limit set by Cisco. Although I can't understand why as the IP space is a very common one in use. Is there any solution except for reconfiguring my DNS, and active directory.
Please respond understanding that I am a mid level capable network engineer, I have worked with CISCO in the past but mainly Enterprise level layer 2 and 3 switches. I am a netwok security person (CISSP) with medium network skill levels.
Thanks,
Rich K, CISSP

Wow - that's unfortunate. Hopefully you'll get something out of it for all of the wasted time.
I should have researched this more before I purchased. Silly me - thinking Cisco was the best...
I probably wasted 4-6 hours, if not more, trying to get their QuickVPN client to work. They finally blamed it on my ISP, who I spent plenty of time on the phone with as well. The funny thing that they couldn't explain though, was that it also would not work on my Spring 3G/4G data card. After this test, I wrote the whole thing off to a design flaw.
In the end, I went back and setup a M$ PPTP vpn for the time being, until I have time to figure out a better solution. I only have a couple of remote users anyhow.
Thanks for the response and good luck to you!

VPN Router to Router with 192.168.1.1 WAN address

I have two WRVS4400N routers I'd like to create a VPN tunnel for.
One gets a WAN IPAddress totally external: 75.32.167.xxx from the DSL modem.
The other one is connected to an ADRAN 676 modem.
This modem has an external IP address (67.155.29.202), but assigns address 192.168.1.1 to the connection to the router.
I have the router configured to assign addresses 192.168.0.xxx to all computers on the LAN.
The VPN setup requires to define the WAN address as the external address, but my router only sees address 192.168.1.1 as the external address (coming from the ADRAN modem)
I hope this is not too convoluted and someone can help me. Following is an attempt at illustrating my setup:
10.10.10.1-->Router1--->75.32.167.147 ---->INTERNET--->
INTERNET-->67.155.29.202--->ADRAN modem--->192.168.1.1-->ROUTER2--->192.168.0.1
Thanks in advance
Rodolfo

You adran modem also operates as NAT router. You have to reconfigure the adran modem for bridge mode. In bridge mode the modem operates like any other simple modem. You then have to configure the router for your internet connection, e.g. use PPPoE with the username and password supplied by your ISP. With that your router will have the public IP address.
Otherwise, you would have to configure port forwarding and IPSec or GRE forwarding on the adran to pass the VPN traffic to the router. However, this may not work at all if the router is not able to handle VPN traffic through your NAT adran modem/router (my guess is it won't do it but I have not tested this).

Can't connect to 192.168.1.1 with WRT610N

Hi, i've been trying to add my sister's new laptop to the authorized MAC adress on the router, but i just can't get on the 192.168.1.1 administration page. When i type the adress in, the page loads for minutes, hours and even days with no result. I tired on the four computers connected to the routers but the page just loads forever and never shows.

Hi, I think I finally found the problems with not getting access to 192.168.1.1, or at least it works on my computer for now. Haven't tried it more than today, but I think this is the problem.
Turn of Linksys advisor program. Then try 192.168.1.1 It worked on my computer. The Linksys advisor loads on startup, and I think I will have the same problem again, if it starts up, so I will try to disable it in startup. I've also configured the network settings on the connection to internet protocol version 4 (TCP/IPv4) to use the following IP address of my computer (192.168.1.X), subnett 255.255.255.0 and default gateway to 192.168.1.1. Without those setting, ie obtain IP address automatically, I couldn't reach 192.168.1.1 You can manually start the Linksys advisor program afterwards, and I had no problems connecting to 192.168.1.1
I have tried every other solution mentioned on this forum, but nothing has worked for me. The most commoned answer is, reset your router or turn off the router, then it will work again. It does, but only for a day, or sometimes minutes, then its back to the same problem, with not being able to connect to 192.168.1.1 I have also downgraded the firmware and are using open DNS, but that didn't help. It seems to me that the problem is with the Linksys advisor program, kind of strange that I have read only one post mentioning that! But of course, I'm not 100% sure, but again, its working on my computer, and I can finally connect to the administration pages again!

What configures en0 with IP address 192.168.2.1 ?

Recently, I realized that (only) "en0" has two IP addresses configured, but I configured only one from System Preferences.
The output of "ifconfig en0" looks as follows:
en0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 192.168.2.1 netmask 0xffffff00 broadcast 192.168.2.255
inet 192.168.100.4 netmask 0xfffffff0 broadcast 192.168.100.15
ether 00:23:32:30:6c:cc
media: autoselect (1000baseT <full-duplex,flow-control>) status: active
supported media: autoselect 10baseT/UTP <half-duplex> 10baseT/UTP <full-duplex> 10baseT/UTP <full-duplex,hw-loopback> 10baseT/UTP <full-duplex,flow-control> 100baseTX <half-duplex> 100baseTX <full-duplex> 100baseTX <full-duplex,hw-loopback> 100baseTX <full-duplex,flow-control> 1000baseT <full-duplex> 1000baseT <full-duplex,hw-loopback> 1000baseT <full-duplex,flow-control>
Also removing the entry with "sudo ifconfig en0 -alias" only works until the system has been restarted at which point it is mystically restored.
My computer has the following network connections:
= en0 ......... (Ethernet 1; connected to local router)
= en1 ......... (Ethernet 2; not connected)
= en2 ......... (AirPort; connected to AirPort Express base station and Internet)
= en3 ......... (Parallels shared network adapter)
= en4 ......... (Parallels host-only network adapter)
= vmnet1 ... (vmWare virtual network adapter)
= vmnet8 ... (vmWare virtual network adapter)
While both routers do provide IP addresses via DHCP for guests all my own IP addresses are manually set.
Does someone know how to remove the "192.168.2.1" entry for good?

I understand that any IP device needs a proper address to be able to be... well... addressed. Thing is that there is already an IP address ("192.168.100.4"), which would be possible to be used for this purpose. That is where I started to wonder.
Because System Preferences -> Sharing -> Internet Sharing tells the Mac to act as a router, and the 192.168.100.* subnet already has a router. They would fight. So en0 needs a new IP address in its own subnet.
Mac OS X, as shipped, does not have a WiFi to ethernet bridge mode.
You can buy a WiFi base station and configure it for bridge mode (turn off NAT and DHCP services) which will then allow you to extend the existing subnet.

Problem with my linksys WRT120N i can't connect to the address 192.168.1.1

Hello friends
i need help cuz i can't connect to the address 192.168.1.1
i didn't change the address 192.168.1.1 to an other address but i can't connect to this last i want to change my options
i really need help plz

Make sure that the computer is connected to the router on the Ethernet port..Now,check the ip address on the computer....Click Start >> All Programs >> Accessories >> Command Prompt...A black box will appear(Command Prompt)...In the Command Prompt window type ipconfig and press 'Enter'...Look for Ethernet Adapter Local Area Connection IP Address , Subnet Mask and Default Gateway...
IP Address should be 192.168.1.x, Subnet Mask : 255.255.255.0, Default Gateway : 192.168.1.1 (assuming your router is 192.168.1.1)...
If you get the above mentioned IP Address, Subnet and Gateway Address then you should ping the Gateway, type ping 192.168.1.1 and press Enter...If it gives you request timed out then disable any firewalls, security softwares on the computer...
If you get 4 replies then,Adjust the Browser Settings on the computer....Open an IE, click Tools >> Internet Options, then delete all files, cookies, history, forms...Goto "Connections", make sure Never Dial a Connection is checked, click on LAN Settings and make sure all the options are unchecked...Once you are done click on O.k...Close the IE and re-open it...

Cannot access 192.168.1.1

I have tried on my wireless and wired computers. I still can't get access. "timed out" message.
Note the following. I did upgrade the Firmware not too long ago. I can surf the internet on both computers. I have a WRT54G Router.
Here is my ipconfig information:
Ethernet adapter Wireless Network Connection:
Connection-specific DNS Suffix : domain_not_set.invalid
IP address : 192.168.1.100
Subnet Mask : 255.255.255.0
Default Gateway : 192.168.1.1
If you need more info, please let me know.
Note also that when I disable my firewalls, I still get the same "timed out" message. Also note that when I upgraded the firmware, I don't remember resetting the router, if that has anything to do with it..Thanks!Message Edited by Volodya on 02-06-200706:12 AM

Some times a hard reset will fix this problem. Have you tried pressing and holding the reset button for 30 seconds? I know Linksys documentation says 10 seconds but 30 seems more the norm.

Other devices: MacBook Pro defaults to 192.168.2.100 and won't connect. Says it is using DHCP and also says that the router address is 192.168.2.1. I try renewing the DHCP lease and same thing keeps happening. What might I check or change that will ensure I can have a good, consistent wireless connection to this router/modem combination.
Thanks for any help!

The Linksys router is connected to the embarq 660 modem at the 'internet' port on the back of the router and to the 'ethernet' port on the back of the modem. The Mac G5 is plugged into one of the numbered ports on the back of the router. Nothing else is connected to the router. The MacBook Pro is a laptop I'm trying to connect wirelessly. I have the modem connected to the wall jack (the DSL connection) and to the router as described already. I don't think there's anything wrong with the wiring.

Can't connect to 192.168.1.1 EA6500 or the Internet

Hi
Yesterday my router froze and wouldn't do anything, so I rebooted the router. When it got up and running again, I couldn't connect to the Internet. I got the error 502 - bad gateway.
I can't connect to it at 192.168.1.1 or linksyssmartwifi.com. I can ping 192.168.1.1, but not 8.8.8.8.
Ipconfig /all
DHCP yes

Subnet 255.255.255.0
Default gateway 192.168.1.1
DHCP server 192.168.1.1
I've tried flushdns, release and renew and it seems that the DHCP server from the router is working.
In windows it seems that there are an Internet connection.
I don't understand this, I can't visit any websites, but Spotify works.
I'm afraid it's broken and I have to buy a new router. I've triede to reset the router.
I hope that some of you can might help me.

Try disconnecting the router from the internet (WAN port) and plugging a PC directly into one of the LAN ports. After resetting, ignore the smartwifi login, click the two checkboxes, and login manually/directly with the "admin" password and reconfigure.
If you don't want to do all that just yet, try accessing the router from the public IP address assigned by your ISP. That might work

Trying to set up as a router - Changeing to 192.168.0.1

I had a linksys router connectd to my Verizon Fios interface - A wireless router - (that can pick up anything ) - but it died. Got a airport extreme Tried to configure it the same way as a Router handing out ip addresses starting with 192.168.0.1 Thus keeping all traffic comming through the router and not Verizons.
Can i check to see which computers are logged in Allow certain Mac Address and set up Static address for printers lpl ports.
I went through the set up Airport utilites and set up the 192.16/8.0.1 and designated address for the printer and linuxz server but How do i check the actual assigments?

Actually I’ve done this with great success.
I’ve never liked using ISP routers/modems/firewalls for my own network because most the time they lock them down in a way which keeps me from managing my own internal network.
My configuration is an AT&T modem/router then the Apple Router, here’s what I did:
1.)     AT&T Router/Modem:
Turn DHCP off
Turn Wireless off
Open ports YOU need internally to your network in which you require access from the outside. (Port Map).
2.)     Apple Router:
Instead of allowing your router to obtain DHCP from the outside like you would if it was hooked mainlined into a modem, make it static and enter in the IP subnet established by the AT&T router. Mine is something like 192.168.1.2, because 192.168.1.1 is the gateway in this particular setup.
Configuring port mapping and service ports in the Apple router.
Then setup DHCP or Static for your internal network.
NOTE: You’ll have to use two different IP schemes for your home/business NAT, meaning the AT&T to Apple router, in my case, is a 192.x.x.x NAT, but goes no further than this. The NAT in my network is 10.x.x.x. This minimizes confusion on the network part, but also keeps you ‘untangled’ when it comes to port mapping, address assignments, and other issues.
If your Verizon router/modem is wireless, you to turn that off and make the Apple router your wireless gateway.
Message was edited by: Torn-Barb
Let me add this as well: You need to know that the Verizon router/modem you have has to be configured as a ‘dummy’ device. You’re just using it for the internet connection (TV’s if applicable) and nothing more. The Apple router will do everything the Verizon device can do and more.

IP address 192.168.1.255 active every 30 seconds - why?

The IP address 192.168.1.255 is active every 30 seconds - why? I use Virus Barrier and also Little Snitch to monitor network receiving and sending activity... Since I began this process I've been baffled by the fact that this particular IP address, 192.168.1.255, is so active - about every 30 seconds the Little Snitch window shows sending and receiving activity after the the line "cupsd." I assume it's harmless - but since I can't seem to determine why this is happening, I can't be 100% sure... I hoping someone familiar with this network issue can explain why this is happening. Thanks very much.

Hi there,
An IP address starting with 192.168 always is associated with a router. To have items being sent to and from it is therefore normal.
Nothing to worry about.

RV220W PPTP Start IP Address must not be in the subnet of LAN:192.168.1.1/255.255.255.0

Hi,
This is a change done explicitely starting firmware 1.0.4.17. It is not a bug. This appears to be by design. PPTP peer networks are now treated as a routed subnet. It is unlikely that this will be changed.
But nevertheless there is a workaround to configure the PPTP range in the same subnet as your LAN:
1. Configure LAN IP subnet different from what you will use, for example 192.168.2.0/24
2. Configure DHCP pool for PPTP client as needed for example 192.168.1.100-192.168.1.110
3. Go back to LAN interface and change LAN IP to desired one: 192.168.1.0/24 and pool 192.168.1.2-192.168.1.99
4. This way there will be no error on GUI
5. PPTP client will receive IP address from the same subnet as LAN interface of the RV220W

I have checked with ISP, there response is like below:
Those are the NNI to GBNET IPs for Dominican Republic. They are Network IPs. You should be able to ping them-that means they are working.

I have problems with my 7510 holding a wireless network ip address 192.168 etc It says 169. etc

My HP Photosmart all in one (which is only a few months old) stopped comunicating with my Netgear DGN1000 Adsl router a few days before Xmas.
Instead of the 192.168.0.9 ip address that it used before I powered off the router, iit came back with an address of 169.254.249.128; "Configuration source" = "Auto ip"; a subnet mask of 255.255.0.0; and Default gateway of 0.0.0.0; I know these are wrong, so I tried a fixed ip address of 192.168.0.201, a SM of 255.255.255.0; and a DG of 192.168.0.1; This was OK, but overnight, it all went back to the auto ip settings.
I eventually managed to contact HP, and the guy spent 75 minutes with me trying to reset things, and eventually he reckoned that the Netgear router was not allowing the printer access via some ports (which he emailed me a list of) and something he said I needed to tell my isp (Virgin media) “FLOOD DETECTION SET TO OFF” & “SP1 FIREWALL SET TO OFF”
On contacting VM, they were insistant that their router was not at fault - they could open the 12 or so ports, at a cost to me of £60! (I declined this)
HP had told me how to set up for Ad Hoc printing (by-passing the router) which had worked during our testing.
VM had been into my settings for the router, via a remote access device, and checked a few settings, but the only one I saw them alter was changing from CH10 to CH11.
I certainly could not get the printer to accept the 192.168.1.201 after this anyway.
Following this, I reset the printers Network Defaults, and reconfigured the wireless settings. It did seem OK, and running on 192.168.0.9
I have now reset the IP address to Manual on the printer, entering the 192.168.0.9 and 255.255.255.0; and 192.168.0.1;
Touch wood it has held up for a few days, but I havn't switched anything off (but overnight before it went awry!)
I'm not convinced I have got a fix here, and would welcome any suggestions as to what I can still do.
Maybe I have already done some, as I have "completely uninstalled, and reinstalled the HP7510 software on my Desktop PC.
Incidently the printer is set up on 3 PC's in the house - a desktop running W7 HP 64 bit, a Notebook (same OS variant) and a Laptop running W7 HP, but 32 bit.
All were unable to print when I was having issues.
I would welcome any suggestions to get a more permanat fix. (I would rather have found a definite fault) I have other routers I could try, or I could open ports, but my question is - If I needed these ports open, and other settings altered (Flood detection etc) why did the printer work for the first few weeks I had it set up, and why did powering off the router cause such issues? (suppose I need to power off the router again in the future - it does happen)
Thanks
Dave

Hey Dave,
Great post with good information.
As you mentioned, the printer came back with a 169.xxx.xxx.xxx style IP address. This is normally produced when the device is not able to get a complete connection with the router, thus the router gives it a temporary internal IP address.
The normal suggestion when a printer stops maintaining a connection is to set a Static IP. This is done by using the manual IP feature you mentioned using. This locks the device to those network settings and even when the network is restarted the information is retained. This should be the fix to the issue.
Hope this helps.
