SQL uses tcp and udp ports 1433 and 1434
So i think you should be able to load direct using the virtual and bind commands with appropriate ports specified. A sample would look like this
virtual 10.10.10.1:1433:0:udp is
bind 10.10.10.1:1433:0:udp 10.10.10.2:1433:0:udp
Hope that helps. Give it a try!
