Proper Setup for Multiple IPs

[kohenkatz]

I know this has probably been discusses before but I have been searching the forum for a couple days with no success.  Can anyone point me in the right direction?

I have a single pfSense box set up with two WAN's as Load Balancing, one is DSL, the other is T1.  Each has a bunch of IP's available for 1:1 NAT.
I am unsure how to set up Virtual IPs, i.e. which type to use.  I want each of my servers to receive an IP from the DSL and if I can, from both connections.

If it helps, DSL is Verizon Business and T1 is Paetec.

Thank You.
