Access Tomcat on Solaris 9 through Linksys router

Hi everyone, thanks in advance for any help or comments.

I'm having difficulty accessing a tomcat server from outside our office network.  We are on high speed cable.  I have no problems connecting to an IIS server on a windows machine.  Our office has an ip say, 11.11.11.11 and I'd like to be able to view the tomcat machine from the outside world.

We're running tomcat on port 8080 on a solaris computer in our office network.  The internal address is 192.168.1.200.  When I go to 192.168.1.200:8080 it works fine.  When I go to 11.11.11.11:8080 it works fine when I am inside the office.  When I go to 11.11.11.11:8080 from an external site, or say I use a dialup account.  It doesn't work.

We have a linksys router BEFSR11 with the latest firmware.  Router settings that have been tried.
- making the DMZ 192.168.1.200
- forwarding port 8080 to 192.168.1.200 port 8080
- block WAN request (disabled)

I think that this could have something to do with the solaris configuration and needing to put the external ip 11.11.11.11 somewhere but obviously, I'm not really sure.

If someone could point out what I can do to get this working I would really appreciate it.

Thank you.

If you are accessing it inside, the I assume there is no configuration needed on tomcat. It would be on the router, or firewall. I think you need to indicate a forwarding for a specific external IP (if you own it) to internal IP. This is basically called NAT (network address translation) so you need to make the translation between IPs, nothing to do with ports.
