NAT and lack of a routing table entry in the first router... The first router has no knowledge of the network behind your linksys because it is NAT'ing and you do not have a route statement in the first router relating to the network on the second router. The devices behind the second router can reach devices on the first router because it is NAT'ing the traffic and also because the second router's default route sends its traffic to the first router to route. There are ways around it such as disabling NAT (I don't think you can do that on the Linksys router you mentioned) and adding a route statement in the first router. You would also then have to program the first router to perform NAT for the second router's LAN network as well. This makes for an overly complicated setup for a home user that has limited network experience. Setting up the routers LAN to LAN is the easiest way to resolve your issue, even though it is not all that simple either.

Thank you so much for the link, Gilbert. I'll look at it as soon as I click send. I do have one question though, why will it talk one way but not the other?

Mike, what I was trying to walk you through is outlined on several web pages if you do a search. I have included one of those links for your convenience. Your provided modem/router (router 1) uses either DSL or Cable for its WAN/Internet port. I would heavily suggest against you making any changes to router 1. SOHO routers typically have a cluster of ports which can be lumped together under the title LAN. Most SOHO routers will have a port off the side from that grouping to help you distinguish the fact that it is the WAN/Internet port.
