Hello Ken,

I'm not familiar with the SuperPipe 155 but in a P130, P75 etc. NAT only
applies to 1 connection profile. So if you could configure the SuperPipe to
handle the class C on one connection profile and NAT another it should work
fine, but I don't think you can have both on the same connection profile
unless the155 handles connection profiles differently than the P130, P75 etc.
