Hi guys, this is a tough one but I figure you can get it sorted.
I am trying to either port forward or DMZ a server box. I can get from anywhere in my LAN to anywhere, all my boxes are set up with SSH pubkey auth. However, I cannot get inside my LAN from outside, all I get is "connection refused".
The ISP and DSL provider both swear they aren't blocking any ports. Each one naturally blames the other one so no help from there.
When I DMZ the box I want to reach from outside, canyouseeme.org reports that port 22 is open. But if I run nmap inside my LAN it says it's open but from outside it's closed. How is this possible?!
I have no idea to troubleshoot this, but I would like to prove my router is screwing the works and I don't have another router to try. I suspect the router because when I telnet from inside my lan to ports 23 or 80 on my external IP address I get the router's management interface rather than the connection refused I would expect since I'm not running a webserver on the server box. And nmap says the port is closed and I trust it a lot more than I trust some website.
Any ideas? Thanks!
