You need to have two different IP addresses. There are two IP
stacks. If both have the same address, one stack will get all the
packets and the other none.

There are a few solutions to the problem.....

Use bootp and DHCP, one for each IP address and configure the servers
with different IP address ranges.

Statically allocate an IP address for one of the stacks. Get the other
