"Cant connect to server" UBUNTU

Hi, i am hosting a tekkit server on my ubuntu VPS. for some reason the server starts perfectly and DOESNT say "failed to bind to port" infact it starts very fast and perfectly. BUT, when i try to connect i cant connect to server. PLEASE HELP!

 

Is it running a firewall? If so, you'll have to make an exception for port 25565. Also, make sure server-ip in server.properties is left blank.

 

its blank and im not sure the commands to add an exception to my firewall. wouldnt it say couldnt bind to port though? Please help

EDIT: Im also using iptables.

 

You need to port forward your server port. Ports are used locally on the computer when you start the server. It can bind to the port perfectly, but in order for someone outside of that network to connect to the server, it has to be forwarded. You can google port forwarding for numerous guides on it.

 

This page can help you with iptables. It wouldn't say that it can't bind to the port because it is able to bind, however network traffic to the server from outside sources can't reach it due to iptables. For easier management and better security, I recommend installing a software firewall such as CSF.

Taketheword On VPS, most ports are normally already forwarded, especially if you have a dedicated IP.

so would i do:
sudo iptables -A INPUT -p tcp --dport 25565 -j ACCEPT
sudo iptables -A INPUT -p udp --dport 25565 -j ACCEPT

??

 

Try reading the stickies on this forum, however, you should be seeking help from Tekkit for your issues running their server.
