Are we suppose to be able to view the nat translations taking place when
using a NAT Virtual Interface.
Here's me pinging google using a NVI, but I can't see any NAT
translations taking place???? The translation must be taking place
because my PC has address of 192.168.2.2 (gets natted to 210.15.230.x)
and I'm getting replies from google.
