Dedicated - No One (but me) Can Join

[elsoqo]

Arr mateys. So I've been trying to set up a dedicated server.. so far so good with plugins and such. However, when I try to get my friends to join they get the error message that the server isn't responding.

I've already tried forwarding this set of ports:

UDP 1200 1200
UDP 26901 26901
UDP 27000 27015
TCP 27020 27039
UDP 27015 27015
UDP 27020 27020
TCP 27015 27015

*edit*
T/U 3478
T/U 4379-4380
T/U 27000-27050

Plus, I set myself as DMZ (and restarted) to no avail. Also set sv_lan to 0, I set the region to 0 (East Coast), still no one but me can join my server.

At one point I left the server running a few hours and found it was down. I typed heartbeat into RCON and brought it back up, so it seems like that isn't getting automatically done? I was under the impression it was default for heartbeat to be used every 30 seconds.

Wondering if you fine people had any ideas. I've been able to set up dedicated servers, and people have been able to join alright, but those are on non-HL2 games.

So, using that site I see that my port forwarding doesn't work. And.. possibly never worked? I don't understand, then, how my past servers worked after I set up the port forwarding rules. I set up the rules for port forwarding in my router, yet these ports are not actually opened. Plus, for what it's worth I set myself as DMZ. Is there something else that could be interfering? Firewall, admin priviliges, anything?

The only ports I see opened are some ports for Skype, which I assume was always there since I have to go through my ISP's dashboard (Optimum) for the router instead of accessing the router settings directly myself.

Edit- it's something with my ISP, so once I get that resolved it might be fixed. If I don't reply it's obviously resolved :P

Alright, so I've been looking into this on my free time over the past few weeks, and have tried various tweaks and fixes and still nothing.

I can host 7 Days to Die and other *dedicated* servers just fine without Hamachi. For any HL2 based game, no one can join my dedicated servers unless we use a tool like Hamachi.

I am set up as the DMZ on my router settings (I have a static IP) AND I port forwarded 27000-27050 both UDP/TCP and still don't see a change. I'd appreciate any help on this.
