 ^^^^^^^^^
This is a problem. I don't know of any Linksys router that acts as a DNS 
server. When you setup your router, there is a place to put your ISP's 
DNS servers, and another place so that the DHCP server in the router can 
relay the DNS server info to DHCP clients. For your local net, add the 
3(?) ( you have phoenix1 listed twice above) machines to your hosts file 
on the Windows machines as well as the linux machine. In your 
/etc/resolv.conf, add your ISP's DNS server entries. Your other 
alternative is to configure DNS on you linux machine and use that as 
your primary DNS server, and your ISP's DNS servers as secondary.

Do you really have 2 machines named phoenix1?
