I'm trying to open port 21025 so I can host a server for Starbound on my computer. I enabled port forwarding on my router (an ASUS RT-N66U firmware 3.0.0.4.380_3831), I set a static IP, I forwarded port 21025, and apparently the port was still closed. After several failed solutions I turned off my computer and put it into DMZ and tested several ports and they were all closed still, I pulled my computer from DMZ and turned port forwarding back on for the moment.
After awhile I began to think that my router wasn't the issue, mostly because my router had a port forwarding log and the first three lines implied that the ports are open
Destination Proto. Port range Redirect to Local port
ALL TCP 21025 192.168.###.### 21025
ALL UDP 21025 192.168.###.### 21025
So I tried making rules on my firewall to allow that specific port, both for incoming and outgoing connections and the port was still listed as closed, that did not help at all, lastly I turned off my AV (Kaspersky) and tested if the port was open, and it was not. I've also gone into command prompt as administrator and typed "netstat -an" and there were no connections listed that had the port 21025. Eventually I tried to port forward using another computer (same OS as the original, Windows 10), which didn't work, I actually found an old laptop that I use for testing Linux stuff and installed the newest version of mint, gave it a static ip, changed the port forwarding to its ip, then tested the port and it was still listed as closed.
The only thing I haven't actually tried that I can think of is turning the routers firewall off (which I have a feeling my dad would rather I not do this, unfortunately there is no obvious way to make an exception in my routers firewall.)
My own guess is my service provider is blocking the port, honestly since I'm leaving for college in like a week that is far too much effort to fix my problem so if anyone has an alternative suggestion then I'll try that. If all else fails I can use something like LogMeIn Hamachi to host a lan server, that just requires far more effort on my friends part so I'd rather not.
