WRT54GS Routing Issues

Here is my problem, i just moved in with a family member, who has a
very basic setup.
High Speed Internet Connection, Wireless Router (Linksys WRT54GS) and
one computer.

I have a windows 2000 domain setup, with a windows 2000 server as a
router.

Active Directory is installed & configured on a seperate system and
there is a backup dc present.
The primary dc is the DHCP server for LAN2 and both dc's have dns
installed. DNS servers are setup to foward to ISP's DNS servers. There
is a wireless to ethernet bridge between LAN1 and LAN2. NAT is setup
and working on both routers. LAN2 can access resources on LAN1. For
some odd reason LAN2 can not access the internet. I was able to work
around this issue by installing a proxy server on LAN1.

How can I get LAN2 to connect to the internet without a proxy server?
