How to get my other IP to work

I have a CentOS server with the main IP (eth0) 85.17.187.152 and a virtual interface (eth0:1) with the IP 85.17.187.136. As you can see they my virtual interface (eth0:1) redirects to my normal interface (eht0). But when I try to connect to the IP of my virtual interface (85.17.187.136) it doesn't let me connect to my minecraft server. How can I get this to work?

 

Sounds like a problem with the NAT (Network Address Translation) im no expert on that tho =/

 

Just some ideas.

You are trying to get the same CraftBukkit server to answer on both IPs? If so make sure server-ip= is blank in server.properties.

Is there any kind of firewall external to your server that would require the port to be open for that IP?

If my memory is correct, iptables just treats the virtual interface the same as the physical, but I could be wrong. Maybe worth looking into.

Is SELinux set to enforcement mode?

 

I have set my server-ip= to 85.17.187.152. So if I make it blank it should work?

 

Yes. What the server-ip= setting does is tell the CraftBukkit server which interface you want to bind too. By leaving it blank it will bind to all interfaces.

 

Thanks for the help! I changed my server-ip= to blank and it works now!
