How to Set Up Multiple Routers

However, this post gives me hope. Verizon's tech support claimed it's not at all possible without a router for each subnet, which sounded absurd. I question the need for a router at all, really. But why get more complicated than that? You aren't gaining anything. People get a little crazy with subnetting and VLANs sometimes. I guess the primary reasons we're using the router are: I would think the setup my boss is attempting to implement is fairly common.

I understand subnetting hosts on a switch which still requires a router to allow communication between VLANs , and routing traffic between multiple LANs seems like it should be just as easy. The only part that's confused me is setting up three private IPs on a single router; configuring it to act as a default gateway for more than one LAN.

I'll have to find a time when I can take down the network and mess around with the router settings. If your router has 4 L3 ports you can just assign an IP from each network to each port and then tell the devices on that network to use that IP as the default gateway.

I do it with cisco equipment all the time, usually where the client wants a guest wifi network seperated from their lan and sourced from a different IP on the internet. Any higher end equipment should be able to do this, it may be hit or miss with SOHO stuff though. If you don't have 4 L3 ports but you have vlans you can probably replicate the above with switched virtual interfaces.

Let's say you have a router with 1 wan port and 4 switched lan ports that supports vlans. You can plug the internet into the wan port, assign IPs on each network to a different vlan interface then set the physical switchports as corresponding access ports.

You'll need to connect the servers to access ports on the switches instead of the router and then configure the LAN port on the router and the physically connected switchport as a vlan trunk port to get all the applicable vlans across. So your explanation made perfect sense! I'm guessing the hard part will be in the actual implementation. I might be able to convince my boss to get one of these and do option number one and save us some hassle. I just have to figure out a way to convince my boss that taking down the DDNS server for about an hour while I try to configure the network is worth it.

Sat Oct 12, Plan your DHCP pool. Plan your static IPs. Find out if your secondary routers have a "bridge" or "access point" mode - if not then you'll need to give them static IPs and disable DHCP on them. I thank you both very much. I guess I was wrong thinking that going from 2 to 3 routers would cause additional complications.

Power on the router. Attach your computer to a LAN port on the second router using an Ethernet cable. Open your Web browser and go to the IP address of the second router. Follow any steps to finish setting it up as found in its documentation. Dustin Lamb contributes to various online publications, specializing in computers and technology.

Prepare to Configure

Configure the wireless settings if it's a wireless router. Assign a name to your network and enter it into the SSID field. Set an encryption type of WPA-2 and type a wireless password that devices must use to connect to the network. Connecting two home routers via wireless is also possible, but in most configurations the second one will only be able to function as a wireless access point instead of a router. The second router must be set up in client mode to utilize its full routing functionality, a mode that many home router's don’t support. Once you power cycle all network, you can begin using multiple routers. The new router should show up to wireless computers in the area.
