ubuntu LAMP server, can't access site remotely, locally works by local ip and wan
So I can access the site from the wan ip, the lan ip, localhost on the actual server, but people can't seem to connect to it. I have the server in DMZ mode, and I even opened port 80 in the router as well. I also turned off the default firewall that comes with ubuntu and i do not have iptables. My friend said he was able to ping the box and said that it was app side.
what is their experience when they can't connect? A standard test to divide and conquer the issue would be to telnet to port 80 and see if that connects. You can also run tcpdump on the server to see if any requests are indeed reaching the box.

I believe it just kind of loads for a while and eventually fails, not sure what message they get, but it does load for a while.
we'd really need more than that. if it just doesn't fail instantly, it could be a network timeout issue, which could certainly make people believe it's loading in some form when it's actually not.
right, so a routing or firewall issue at some place. run "tcpdump -vn port 80" on the server when you try to connect and see if the server itself sees anything. even if iptables is knocking it on the head, tcpdump will see it, so if tcpdump doesn't see anything, the traffic is not reaching the box.
