OK, now I get it...I wasn't sure what machine you were using...so you're
using a Mac with built-in Ethernet via an AAUI transciever.

yes

yes

Sorry, I should have said /etc/ifaliases. You need to create a file
/etc/ifaliases I have in it the form:
address interface netmask
or in your case
192.168.1.1 sn0 255.255.255.0

Yeah, make your ipnat.conf say
map sn0 192.168.1.0/24 -> 216.164.32.41/32 portmap tcp/udp 10000:40000

It should as far as I can tell
