I am trying to set up a server on an old 1998 Compaq desktop, now running Debian, and so far the software is working fine, but am having some trouble getting my router configure so that computers outside of my LAN can access it. My router has one IP address that all the local address use, and I have tried to forward port 80 for http and port 22 for ssh, and I still can't access either from outside the LAN. Also the sites that check for open ports say that both of those ports are still closed. Any ideas of what I could do to fix this. Have googled for days with no avail.
