Hi

I followed the Linksys instructions for setting this up – http://www.linksys.com/us/support-article?articleNum=132275. Both my routers are WRT400N. On the main router, I can connect to the internet. The routers are in different subnets. On the secondary router I can share with other pc's on the lan but can not connect to the internet. From the secondary router, I can get to the web admin of either router.

I then contacted my ISP to see if there was something I needed to do on the secondary router since my interenet connection uses PPOE. He recommended I do the following which didn't work for me. Wasn't sure if I entered all the fields correctly. I can provide screen shots if necessary. Router A would be the main router, Router B would be the secondary router.

ISP-Internet < --- > RouterA < --- > RouterB

RouterA
WAN: PPPOE CONNECTION
LAN: 192.168.1.0/24

RouterB
WAN: 192.168.1.10 [static_IP]
LAN: 192.168.2.0/24

RouterA will be handling network address translation (NAT) which is a setting on the linksys router which is set by default.. I believe they call it "gateway" mode or something to that effect.

RouterB will be a simple router with a static IP defined on the WAN interface. You'll also need to change this mode from gateway to router under the "Advanced Routing" tab.

RouterA will need a static route so that it knows where 192.168.2.0/24 is:

RouterA:
Destination Network: 192.168.2.0
Mask: 255.255.255.0
Gateway: 192.168.1.10
Interface: specify correct interface
