A bridge? A switch? Another router?

I had a internet modem connected via ethernet cable to a Linksys router (the wireless ability had been deactivated) and then I ran from the Linksys one ethernet cable to one Apple Express (N) and another ethernet cable to another Apple Express (b/g for some G3 Macs). The internet stopped working so I plugged the modem directly into the N Apple Express. I guess I need to get rid of the Linksys. What should I get to replace it so I can run the N and the B/G Apple Expresses again? A bridge? A switch? Another router?
Thanks,
P.Hyland

When you plugged your Express devices into the Linksys router, did you first configure them to act as a "bridge"?. In other words, the Connection Sharing setting in AirPort Utility must be set to "Off (Bridge Mode).
You would need to do this for both Express devices as follows:
Open Hard Drive > Applications > Utilities > AirPort Utility
Click Manual Setup
Click the Internet icon at the top of the setup page
At the bottom of the next page, look for the setting for Connection Sharing. This must be set to "Off (Bridge Mode) whenever the device is plugged into a router.
Chances are, your Linkys is fine and the Express devices were not correctly configured to connect to the Linksys. If you connected the Expresses to your old Apple router (I'm assuming it has LAN ethernet ports as well), they will be configured the same way. So, whether you use the Linksys or the Apple, configure your Express devices as above.
So, your network will look like this:
Modem > Router > Express Devices > Computers can connect by wireless or they can connect by ethernet to the Router.

Router vs. bridge vs. switch...

My router is in the basement, I buy for 35/35 and I only get speeds of 18/18 wireless (wired 42/20), thats issue #1 .
Issue #2, I have 1 cat5 wire going from router to 2nd floor and want wired setup to my tvs for netflix etc, ps3 and printer for best speeds, possible since I lose so much speed on wireless. My question is, what's best solution for 2nd floor tvs, gaming, printer?, connect cat5 on 2nd floor to another router vs. a bridge vs. a switch?
thank you....
Solved!

#1. 18/18 is pretty typical for 802.11g. If you want faster wireless speeds, you'll have to upgrade to 802.11n.
#2. Connection methods in order of preference:
cat5
MOCA bridge

EA6300 - Cascading the Linksys router to another router (LAN-LAN) - Does not Bridge built in Wifi AP

Regarding:
http://kb.linksys.com/Linksys/ukp.aspx?pid=80&vw=1&articleid=3733#
Cascading the Linksys router to another router (LAN-LAN)
The Bridge mode function on the EA6300 does not bridge the Wifi AP radio to the network.
The ethernet ports are bridged, and the router can see network devices and wifi devices connected to itand ping devices in both directions , but Wifi clients connecting to the unit running in bridge mode are not "bridged" to the network.
~
Using the built in webpage of the router, all devices can be pinged.
Ethernet RJ-45 devices plugged into it can ping the unit and pull up the units config webpage, but not ping wifi clients connected to it.
Wfii devices connected to its access point radio, can pull up the units config webpage, but not ping ethernet RJ-45 devices connected to it.
If there is a bridge, then the bridge is broken in half and not functional.
~
All devices are set with IPs on the same subnet, 192.168.2.x
~
I have a Netgear router in Bridge mode, and it works fine, connecting the wifi access point and RJ-45 ethernet clients together like it should be, so I know how Bridge mode... should work...
But it doesn't on this unit, it is not working completely out the factory door. It will bridge one Router to another via the RJ-45 ethernet ports, but its own AP radio is no longer bridged and connected (like when running in NAT
Note that doing cascading using NAT as described under "Cascading the Linksys router to another router (LAN-WAN)" works fine.

Hi,
There's no WLAN bridge feature on the new Linksys Smart Wifi routers. You might also like to check and review these articles about Bridge Mode:

Using another switch or router with TC???

Do you use another ethernet switch or router with an integrated ethernet switch with your TC??? How do you have things setup?
BTW: I'm running out of physical ethernet ports and I need to use Vonage...
R

If you're out of LAN ports then yes, you need a switch. Plug it into your TC and plug other stuff into the switch. Simple.
When buying a switch, remember one of its ports will be occupied by the connection to the TC. For example, if you're using all three TC LAN ports, buying a five port switch results in a net gain of only three ports: one of them is needed for the uplink, and the one you had to unplug from the TC must now be connected to the switch... three remain.
Fortunately they're not expensive.

Switch before Router?

Currently, my cable modem is in my basement closet. I have a wireless router in the 1st Flr Den connected via Cat5 going into the basement closet. All rooms have coax and Cat5 tht terminate in the same closet. In the Den, I have have 2 PCs, a network printer and NAS connected directly to the router. The number of networked devices outside of the den has grown and several of them need to be hardwired. My thinking is to add a switch in the basement closet with enough ports to handle the devices that need to be hardwired and connect the existing wireless router to one of its ports. I'm not sure if I can add a switch before the router since all installation references I've reading say the switch is installed to one of the router's port. My goal is to have a single network in the house so that all devices could see each other.

It depends on whether your modem is a simple modem or a modem with router included. Often modems are full routers, too, although people don't notice.
If it is a simple modem, you probably cannot connect a switch to the modem. Any device which is directly connected to the switch and modem connects directly to the internet and has a public IP address. For many ISPs it is a paid option to have multiple public IP addresses at a time, thus it usually does not work except for a single device at any time.
Moreover, even if you have multiple public IP addresses the computers are fully exposed to the internet. You don't want to use windows file/printer sharing on computers directly connected to the internet. It is a high security risk.
Thus if you have a simple modem only you most likely need a router from which you connect. If you don't want to move the wireless router down to the modem and you don't have a second line between the current position of the router and the modem you must get another router which you connect directly to the modem and from which you go into the wiring closet. You can setup the wireless router as simple access point to create a single LAN.
In case your modem is also a router you can simple rewire and reconfigure the wireless router to set it up as access point like this. Now the modem/router is the only internet gateway for your LAN and the wireless router operates as simple wireless bridge into your LAN.
To find out which kind of modem you have you can make this modem check. If the IP addresses you'll find are identical your modem is a simple modem. If not, the modem is also a router (well, of course unless your ISP uses private IP addresses which would be rather unusual).

Possible to simultaneously use time capsule for backup + another router for internet?

I will soon be moving into an apartment in which my landlord provides wireless internet through her own router.
I also have my own Time Capsule, which I'd like to continue to use to back up my Mac via Time Machine.
Is it possible to connect to both my Time Capsule (for backup only) and another router (for internet only) at the same time?
If not, can anyone suggest a good workaround?

I've done a little research, and it looks like I might be able to wirelessly daisy chain the two routers, using WDS (wireless distribution system), assuming my landlord's router supports it, but that this would drop the speed of the internet significantly: https://discussions.apple.com/thread/2623802?start=0&tstart=0
It works extremely poorly and the landlord would need to agree to it.. plus it would require use of WEP security which is hackable by children with internet hack kits in about 2min flat. Don't go there. Apple have made their products incompatible with most other routers. So any suggestion of a workaround will involve spending some money on your part.
You could buy a airport express and plug that into the main router by ethernet.. again if allowed. Your TC can do wireless bridge to another apple product very well. Messy but could work. It is not that expensive to get a second hand AEBS and use that. You don't need the latest products but wireless range would be better in the AEBS than AE.
So I'm still wondering: Is there another workaround? Is there a way to get my mac to connect to my time capsule (for backup) and another router (for internet) simultaneously, or is that just technologically impossible? If it's impossible, is there another solution?
You cannot wirelessly connect to two different wireless devices at once on one client. You need to either have a second wireless client in the laptop.. for instance a USB stick which can be fairly tiny nowadays. It is just you need to find one with Mac drivers. Or the TC must have internet connectivity. You could get that by buying a wireless bridge, and using that in your room, with the TC plugged into it. Universal wireless bridge devices are fairly cheap, but can be a pain to setup. Look for products that work with the main router and use as fast a speed as possible. It can be a tricky setup as you need the wireless bridge working on one channel and the TC working on another. What I am suggesting is the WDS solution you found but using two different boxes to do it. And not using WDS at all, unless the main router is suitable, but rather universal bridge.
The hassle of all that suggests to me,, I would go for the wireless stick, so your Mac laptop has two wireless clients.

I have no idea if this works just to show you what I mean. Please do research it yourself.
An ethernet connection to the TC is far superior solution albeit would require you to plug and unplug it.

Switching my router back and forth from dsl to cable

I have my router hooked up on my home computer with a cable modem. On the weekends, I travel to Charlotte, and take my modem with me, so I can use my laptap while I'm there. The computer there has dsl, and I have to completely reinstall linksys advisor and configure the router, then I have to do the whole thing over again when I get back home for the cable modem. Is there and easier way for me to switch back and forth, or should I just buy another router? Thanks.

hehe..he's right... each ISP have unique requirements to work...so saber_tooth is right!

Branch office setup with L3 switch and router with IOS security

Hello,
I am in the process of putting together a small branch office network and I am in need of some design advise. The network will support about 10-15 workstations/phones, 3-4 printers, and 4-5 servers. In addition we will eventually have up to 25-30 remote users connecting to the servers via remote access VPN, and there will also be 2-3 site-to-site IPSec tunnels to reach other branches.
I have a 2911 (security bundle) router and 3560 IP Base L3 switch to work with. I have attached a basic diagram of my topology. My initial design plan for the network was to setup separate VLANs for workstation, phone, printer, and server traffic. The 3560 would then be setup with SVIs to perform routing between VLANs. The port between the router and switch would be setup as a routed port, and static routes would be applied on the switch and router as necessary. The thought behind this was that I'd be utilizing the switch backplane for VLAN routing instead instead of doing router-on-a-stick.
Since there is no firewall between the switch and router my plan was to setup IOS firewalling on the router. From what I am reading ZBF is my best option for this. What I was hoping for was a way to set custom policies for each VLAN, but it seems that zones are applied per interface. Since the interface between the router and switch is a routed interface, not a trunk/subinterface(s), it doesn't seem like there would be a way for me to use ZBF to control traffic on different VLANs. From what I am gathering I would have to group all of my internal network into one zone, or I would have to scrap L3 switching all together and do router-on-a-stick if I want to be able to set separate policies for each VLAN. Am I correct in my thinking here?
I guess what I am getting at is that I really don't want to do router-on-a-stick if I have a nice switch backplane to do all of the internal routing. At the same time I obviously need some kind of firewalling done on the router, and since different VLANs have different security requirements the firewalling needs to be fairly granular.
If I am indeed correct in the above thinking what would be the best solution for my scenario? That is, how can I setup this network so that I am utilizing the switch to do L3 routing while also leveraging the firewall capabilities of IOS security?
Any input would be appreciated.
Thanks,
Austin

Thanks for the input.
1. I agree, since I have only three to four printers, they need not be in a separate VLAN. I simply was compartmentalizing VLANs by function when I initially came up with the design.
2. Here's a little more info on the phone situation. The phones are VoIP. The IP PBX is on premise, but they are currently on a completely separate ISP/network. The goal in the future is to converge the data and voice networks and setup PBR/route maps to route voice traffic out the voice ISP and data traffic out the other ISP. This leads up to #3.
3. The reason a router was purchased over a firewall was that ASA's cannot handle routing and dual ISPs very well. PBR is not supported at all on an ASA, and dual ISPs can only be setup in an active/standby state. Also, an ASA Sec+ does not have near the VPN capabilities that the 2911 security does. The ASA Sec+ would support only 25 concurrent IPSec connections while the 2911 security is capable of doing an upwards of 200 IPSec connections.
Your point about moving the SVI's to a firewall to perform filtering between VLANs makes sense, however, wouldn't this be the same thing as creating subinterfaces on a router? In both cases you are moving routing from the switch backplane to the firewall/routing device, which is what I am trying to avoid.

Connecting to mass storage and printers on another router

I have my wireless router connected to another router that router is connected to the internet. My wireless connection works fine getting to the internet, but I am unable to see the other items connected to the first router. This would be my network printer and mass storage. What can I do?

Windows uses a protocol called SMB to connect to network shares. You will need to route ports 139, 445, and possibly 137 between the 2 networks. Unless you have a specific reason I would dump the non-wireless router. Having 2 routers is asking for problems and making your network overly complicated.

Added another router to UC320 W network

We are currently using a UC320W for our router, phone system, and wireless. We are wanting to add a device for VPN connections. I was wanting to find out if we could disable the routing on the UC320 W and just have it on the lan and the wireless as an Access Point? Basically install another firewall or router in front of it to handle the routing, dhcp, dns, and vpn connections. Has anybody attempted this?
Any help would be greatly appreciated.
Thanks,

We've not found a way to disable the routing on the UC320. What we ended up doing was giving the UC320 its own public IP, then disable the DHCP/DNS options for it and place another router (a pfSense firewall) in parallel with it.

Wireless bridge from hotspot to router

Hi I recently moved into a new building that has some hotspots for Internet connection which is included in the rent price. I have a linksys Cisco wireless-G Broadband router model no. WRT54G2 V1 and I am trying to create a wireless bridge between the hotspot (I have my own Unique Internet identifier) to the router, which is then connected to my desktop using an Ethernet wire.
Can I create a wireless bridge, if yes, how do I do this?
Thanks in advance

The router (WRT54G2 V1) does not have a wireless receiver capability so you will need a separate ethernet bridge.
Your setup should be like this:
(((Wireless connection)))--->(((Ethernet bridge<-wired connection->Linksys router<-wired connection->Desktop computer
I hope that makes sense. XD

Which Switch and Router to choose?

I am interested in purchasing a Cisco Switch and Router, or possible a Cisco Switch Router.
However, I am not sure of what model to go with.
Currently, we have a network with about 200 Workstations and 30 Servers for our Corporation Infrastructure.
Also, for our lab, we have about 50 Linux Based Servers, and 30 Solaris Based Servers, that are part of our Network. We are a Research and Development Company, and we have had issues with the Lab machines bringing down our network, as well as our corporate network adversely affecting the lab machines. What we would like to do is segment the network so that the different areas will be isolated. However, we also would like to have a lot of control over the traffic that will be able to cross from our network into the lab so that users will still be able to run their tests.
Security is also an issue, and it would be great to have more control, and a better view of what kind of traffic is running through our network.
Currently, we have about 8 Gigabyte Switches which are unmanaged (Linksys and NetGear). Our idea was to get a 1 or 2 Cisco Switch Routers, and then split them up into VLANS and cascade our current switches so that we can still make use of them. The other ideas was to just get a Cisco Switch and use our CheckPoint Router/Firewall to do the routing.
Can you give me any advice as to what model of Cisco Product you would recommend?
Is it better to go with a Switch Router, or simply get a separate Switch and Router?
Please note that all of our Machines have 10/100/1000 NICs, so the device will need to be Gigabyte.
Thanks you so much!

You have two choices. Either to use a chassis based solution or to use stacable switches such as a 3750. Are all the cat 5(or 5e,6) runs coming into one centralized location ? Or are there separate wiring closets that you plan to put. If then we need to put separate switches at those locations and run fiber back to the central location which has a chassis based or stackable switch.
If using a chassis based solution, you can get a 4506 (4507 for redundancy, with a redundant supervisor engine). Supervisor engine is nothing but the CPU of the switch. 4506 is a 6 slot modular switch with 2 power supplies for redundancy. You cannot add two Supervisor engines on a 4506 (4507 can).
Slot 1 is always for supervisor engine, the remaining 5 slots you can fill using 48 port 10/100/1000 modules.(48 * 5 = 240). So your maximum port density is 240 ports on a 4506. (Note that there are 4507, 4510 which are similar models with more slots)
If using 3750, you can stack upto 9 switches in a stack using stacking cables on the back side of the switch. Each switch will have 48 ports (10/100/1000) and you can stack 5 switches to get 240 ports.
For the firewall I would recommend using a PIX 515E, (Why go for Checkpoint firewall when you can use all Cisco). For routing between the vlans, the switches that I recommended above are all Layer 3 switches. They will route between the different vlans. You can also configure ACLs to restrict traffic between multiple vlans.

My LMS 3.2 won't detect Switch 29xx , router 39xx and 7200

Hi ,
my LMS 3.2 won't detect my new Switchs 29xx , router 39XX and my 7200 router !!!!
Thanks

First thing you would want to do is upgrade to the latest device package for Common Services (MDF). That can be done under CS > Software Center > Device Update, check CiscoWorks Common Services and Check For Updates.
You can also use CLI commands (my preference) for this:
PSUCli.bat -p cmf -d -dst c:\psu_download -all (will download common services packages to c:\psu_download\cmf)
PSUCli.bat -p cmf -install -src c:\psu_download\cmf -all (will install the packages)
Use the supported device table below to confirm if your devices are or aren't supported:

Layer3 switch and router

I have a network that I need to connect to the internet. All internal vlans point to a couple of layer 3 switches. On the layer 3 switch I connected a router for internet access.
On the inside interface of the router I gave it an ip address of 10.1.0.1 - this is the ip address I want all my lan traffic to route to for internet access.
1. Do I have to give the layer 3 switch interface port a static ip address or just connect it with a cable (the other side is the internal interface of the router 10.1.0.1)?
2. On the layer 3 switch what command do I use to forward all lan traffic to this router, is it "ip route 0.0.0.0. 0.0.0.0 10.1.0.1?
3. Do I use that above command on both of my layer 3 switches or just the one connected directly to the router?
Thanks.

I cant even ping the router, not sure what else to do. To make it even simpler I removed the layer 3 switch connected to the router above and now have only one layer 3 switch (10.1.0.6) and still cant ping the router. All internal hosts can communicate with each other, just need to get all the vlans routed to the internet.
