First, a picture (ascii text is preferred) of the network would help.

Your description of the problem is rather unclear. I don't know what a "virtual
IP address" is (do you mean its an alias IP - as in a second ip address on
the port?). And if its an alias IP, why are you using it. What purpose does an
alias ip in the same subnet serve?

Since the alias IP and the primary IP are both in the same net, you have no way
to make the alias distinctive from a "routing" perspective. This is actually
not a "routing" question.

Most O/S's, in your situation, would use the lowest IP address available in a
subnet as the source address. If that is what is happening you can swap you
alias ip and primary ip.

But again, if I understand what you've written, *why* do you have a primary and
alias IP address in the same subnet?
