You can add routes such that packets bound for certain addresses leave via one interface while packets bound for other addresses leave via the other interface.

If you have routes such that either interface is valid, then the operating system is likely to load balance between the two (but I'd recommend testing this on each system as it can change just due to configuration changes or some patches being applied).

There may be a Win2K-specific way to take control of the load balancing, but that won't be conveniently accessible from Perl.

See the output of "route print" to determine how packets will be routed based on destination address. Use "route add ..." and "route delete ..." to change this information.

You could also try binding the local address of a socket to be that of a specific interface and hope that the operating system will prefer that interface if the peer address could be routed over multiple interfaces.
