Need Help with Linux Hositng issues

[Harcourt]

So im trying to host a server for a group of friends.

I'm good friends with my ex's brother and he has a server in his attic. I got SSH access and DreamDaemon and everything works right. BUT nocone can connect to the server...

Im hosting on port 2055 and im sure that 2055 has be forwarded

See:

But when I host it it starts up fine but none can connect to it and i get a message in the console port 2055 not reachable by byond hub or something.

Additionally im using an unresolved name so it is accessed by: thename.io:2055

I can resolve the IP though if it would make a difference.

I also tried hosting tg to make sure it wasn't my shitcode.

Thanks for the help

have you opened the port on the linux server as well (assuming it's running iptables or something similar)

from my own byond host box (I use port 45000)

oranges@jumphost:~$ sudo iptables -L
