Hi - here is present setup: Linksys BEFSX41 Router1 connected to the internet, and LAN setup is: 192.168.1.100 subnet mask: 255.255.255.240 IP and SUBNET SETTINGS ON THE ROUTER 1 CAN NOT BE CHANGED. So I can not connect more than 14 computers, but I need to connect another 12 computers, so I have another BEFSX41 ROUTER2, to form network2 with more computers.Behind Router 1 is Domain controller, network printers and few workstations . Every computer needs to connect to each other between network 1 and 2 to authenticate with Domain Controller and be able to print. Could you please give an advise how to configure static routing on each interface on both routers to make it possible? Thanks in advance vector

Why not just give router #2 a static IP address in the same range as network 1. This would make it part of the same network and routing should be automatic...depending on the router. Personally, I would use a switch instead of the second router. Daisy chain it to the first router, plug all clients into the switch. Problem solved with a minimum of setup.

If I connect a switch to the first router, I will run out if IP addresses with this subnet mask. So I CAN NOT use the same range or switch -still need a second network.

You mentioned 14 computers in your original post. With the private Class C IP address you're using you have a range of 254 possible host addresses on one network alone. Do you have more than 254 computers in your network?

I'm not sure if you noticed subnetting on the network1 If you are familiar with the subnetting than you you know, that no matter what is your IP - could be class A - with the subnet 255.255.255.240 you can have only 14 hosts, the rest is network address. If you have IP address i.e. class C and the subnet is 255.255.255.0 - YES you can have 254 hosts. But if the same IP has subnet 255.255.255.240 - you have only 14 hosts. Looking just at IP address and what class is it will not give you enough info how many hosts and how many networks you can have with given IP. IP+subnet will give you this info. This was quick info regarding subnetting. Anyway - Router 1 configuration of IP and subnetting can not be changed, and my question is regarding routing and how to configure 2 routers on each interface to connect 2 separate networks
