How to specify outbound IP for specific applications on multiple venets?

I'm having problems with proxy/relay applications such as a BNC. I have a CentOS 5.6 VPS with 2 IP addresses which are virtual adapters (venet0:0 and venet0:1) under venet0.

In these applications I can choose which IP address to bind to (IP address of venet0:1) but when they create an outbound connection, it is done through venet0:0.

These are my current settings (found using webmin):

Interfaces

Name    Type        IP Address      Netmask         Status   
lo      Loopback    127.0.0.1       255.0.0.0       Up
        Loopback   开发者_运维技巧 ::1             128             Up
venet0  Unknown     127.0.0.1       255.255.255.255     Up
      venet0:0  Unknown (Virtual)   xxx.xxx.xxx.xxx     255.255.255.255     Up
      venet0:1  Unknown (Virtual)   xxx.xxx.xxx.yyy     255.255.255.255     Up

Route and Gateways

Destination Gateway     Netmask     Interface   
169.254.0.0 None        255.255.0.0 venet0
Default Route   None                venet0
::1     ::      128     lo

Please can someone help me figure out how to configure the VPS?

Try to remove the default routes you do not want. The command ip route list should give you three entries. For example, on my Debian VPS, I get :

192.0.2.1 dev venet0  scope link 
default via 192.0.2.1 dev venet0  src 10.15.4.62 
default via 192.0.2.1 dev venet0  src 10.15.4.61 

I want the VPS to use 10.15.4.61 for outgoing connections, not 10.15.4.62, so I type :

ip route del default via 192.0.2.1 dev venet0 src 10.15.4.62

Now I have a single default route, and my VPS will use the IP I want.
