Apache Webserver - Cannot Connect from Outside
I am using Debian linux and apache 2.
I can access my apache server perfectly on my host machine, and presumably in the rest of the LAN. It is set to listen on port 80. I have gone to canyouseeme.org and made sure my ISP was not blocking port 80, as well as tried other ports. I have no firewalls running that I know of. ( Does Debian automatically block any ports?) I have forwarded port 80 to my server through my linksys router, and when that didn't work I eliminated the router all together. I get no errors on startup anymore for apache (though I did work through several.) After all of this I still cannot get outside users connected.
I would really appreciate any help, whatever information you need, please tell me and I will post it.
[Edit] I have never really used linux before and thus I understand nothing about its networking, so maybe under the networking area where it has DNS and Hosts and server name/ domain name I need to change things, I don't know...
