It is not for obfuscation. My m0n0wall is just one step before the actual
internet gateway. The internet gateway (and vpn router) will only listen to
m0n0wall and a couple other devices on the 192.168.1.1/24. I need to make
the internet gateway communicate correctly with the 1:1 addresses. 

Apparently packets are bieng NAT'ed correctly with the 1:1 entries I have in
my m0n0wall but the gateway doesn't seem to like it. When the packets go
through a 1:1 do their mac address get rewritten by m0n0wall? Is that what
happens with regular routing? Maybe that's why the gateway can't communicate
correclty with those ips.
