routing

I have a server with two public IPs. Both IPs are added to eth0 using ip addr add. Now I'd like to contact a server which uses IP address filtering. Only requests are allowed which use the second IP address. Is there are way to set this up using the standard route command in Linux? I guess that's not the case.

So the only solution I see right now: Setup a virtual device let's say eth0:0 and bind the second IP address to it. Then I can reference the device in the route command.

Edit: I can't use the second IP as primary one easily as this IP is used as failover IP.
