17 There are two gateways that probably will NAT. The machine itself does
18 not NAT as far as I understood. So there will be no problem with
19 asymmetric routing. Setting up NAT on an internal machine not being the
20 gateway itself would be unnecessary evil. And it would not help this
21 case as you still need to route packets to the proper (still internal)
22 gateway.
