Ok I have a zoom adsl 5551a modem and a linksys befsr41v4 router. I also have an umbuntu server setup and installed with apache and all the good stuff. When I type in the static lan ip of my server I get my webpage up perfect no problems. But when I type in the static IP my ISP gave me (my public) ip I get nothing. It usually times out after about 3 minutes.

I have been working on this for a little bit now and have no idea where to turn. I have a nat rule on my modem set for port 80 traffic. [here is a pic of the rule] 10.0.0.5 is the ip I gave my router. And I have my router forwarding traffic to my server. [here is a link to the forwarding for the router] and 192.168.1.30 is the static I gave my server.

Ok any ideas of where I can look or things to check for? I have done some packet watching but I didn't see anything that pointed me in any direction. Altho I didn't see any traffic of my router sending packets to my server when I try my static public ip.

So you have two routers? That seems kind of unnecessary. I dunno. In the first picture, what does the "0.0.0.0" mean in the "Global Address From" and "Global Address To" fields?

I would suggest using tcpdump on the linux box to see if it is seeing any of this traffic. If not, then clearly it's not a linux issue. after that... it's reading up on the router guides really.

one thing though is that for many routers it is a two stage affair. first you allow the router to accept connections on that port and *then* you seperately forward that connection to the destination.
