You should be looking into a firewall/router with multiple LAN interfaces, and (strongly suggested) support for multiple IPs on the WAN interface. Gentlemen, this is not the way to do this at all. Test it and let me know if it works or not. This is off the top of my head but I think this will achieve what you want.

This should block communication between both sites and since guest(Router B) only needs internet using the external DNS won't even see the Router A's DNS at all. Router A WAN would have ISP DHCP, Router B WAN would have 10.168.1.X\24(You can actually change this to allow only 1 host instead of the whole segment) Then make sure Gateway is Router A WAN IP. You might be able to get away with using 192.168.0.X\24 on router A and 10.168.0.X\24 on router B. The problem in your setup is that because router B is grabbing an IP from router A it has become part of Router A's network now. The only scenario I have seen in wired networks to do this using retail routers is to have a switch before the routers but you will need to have two IPs available from the ISP for this to work.

A guest network will not have the ability to ping and or access the host network. If any one has anything to add please comment. I found that I could ping the computers on the Router A network from Router B but I couldn't see them VIA Windows7 " Network View" 208.67.222.222, 280.67.220.220.ĭNS Empty/ DHCP ON/ Different SSID for wireless and recommend different channels too. I also set the DNS Servers to OpenDNS for some content filtering. On Router A (Has internet connection from modem/DSL etc.) I set this up on two Linksys WRT54G's running DD-WRT hard wired together (I know you can do this with bridge mode as well but I wanted to test my networking knowledge! I thought what a great idea, so I jumped into my Spiceworks community and found some info here and there so I decided to write something out. So I had a fellow Spice head ask a question "How can I provide internet on a second router so no one can see my network but have one internet source?"
