Open port in Solaris 8 (not accessible from outside)

Hello guys,

I've recentrly installed a Tomcat server in our Solaris 8 servers, and while it's properly configured and running already, I can't access the port from outside the network segment the server is on.

I.e., we have 4 servers in the same segment (consecutive IP addresses), and if I try to connect to my Tomcat server from a browser inside any of this servers using http://xxx.xxx.xxx.xxx: port/tomcat-webapp it will successfully establish a connection and display the app. However, if I do it from an off-segment machine, it won't establish the connection.

I ran nmap from my local machine to scan said server, and the ports I'm interested in opening are shown as "filtered". The other thing is, if I try to connect to a port on that same server with no listening daemon, the browser will almost-instatly spit out the connection error, as it won't actually connect (stays at "connecting..." status). However, on the aforementioned port (7080) it will say "Connecting..." then "Waiting for xxx.xxx.xxx.xxx..."...and it stays there for some time until it breaks.

So, I'm guessing that the port is actually opened and ready for service, but somehow it's being filtered/restricted from access outside the segment.

Any ideas on how can I find what's the problem? Unfortunately, the previous sysadmin didn't leave any docs about this (I know...), so I have no idea if theres a firewall up or not. I tried running the "iptables" command, and it says it doesn't exist, so I'm guessing this is not the firewall that's blocking the port.

What other tools/commands/config files should I check out to trace the offending program and "unfilter" the port?

Thanks a lot!
