If you have multiple IPs assigned to your KVM VPS and remote connections are only seeing your secondary IP, you can manually change the settings on your VPS to force traffic over the main IP by default.

Using CentOS as an example, open /etc/sysconfig/network-scripts/ifcfg-eth0:0 and comment out the GATEWAY line. Do this for all eth0:X files (one is created for each IP), then restart the network.

You can also use the following commands:

sed -i 's/GATEWAY/#GATEWAY/g' /etc/sysconfig/network-scripts/ifcfg-eth0:0
service network restart

Repeat the above commands for each eth0:X file (e.g., eth0:1).
