Maybe I'm just missing something in the man pages, but is there any way
to change the source address used for _outgoing_ connections from the
inside of a NAT to one of the external interface's aliases using ipfw /
natd? Something like ...
( lan ) tun0 tun1 ( aliases )
192.168.0.1 ---+---> [-----] -------> 172.16.0.21
192.168.0.2 ---+---> | | -------> 172.16.0.22
192.168.0.3 ---+---> | nat | -------> 172.16.0.23
192.168.0.4 ---+ | |
192.168.0.5 ---' [-----]
... so that requests originating from 192.168.0.1 would appear to the
outside world as coming from 172.16.0.21, 192.168.0.2 as 172.16.0.22,
and everything else on the inside as 172.16.0.23.
I see from the ipfilter docs and how-to that it appears to support this
kind of functionality via its map directive, but I'd rather not have to
switch.
Many thanks in advance.
