It honestly sounds like a routing issue.
Double check your configuration on the router.
Oooh and what version of tomcat are you using???
Check the config file to MAKE SURE tomcat is running on port 8080.
I had a simular issue when using tomcat 4.0 they had distributed
tomcat w/ a config that ran on 8180 so you might want to check that :).
