RE: IPNat and 1 interface

["Mark Baenziger" <markb_(_at_)_e-quill_(_dot_)_com>]

I've had a 2.8 STABLE box ipnatting with just one interface with
an extra IP aliased to the interface.  It works like a charm - I use it
on an
internal test lab to simulate the effect of one of our load balancers.

$ cat /etc/hostname.fxp0
inet 10.1.0.150 255.255.255.0
inet alias 192.168.50.80 255.255.255.0
inet alias 192.168.50.81 255.255.255.0
$ cat /etc/ipnat.rules
rdr fxp0 192.168.50.80/32 port 80 -> 10.1.0.209 port 80
rdr fxp0 192.168.50.81/32 port 80 -> 10.1.0.209 port 80
rdr fxp0 192.168.50.80/32 port 443 -> 10.1.0.209 port 443
rdr fxp0 192.168.50.81/32 port 443 -> 10.1.0.209 port 444

Hmm.. How would this work?  You need two interfaces--a NIC and a modem
or two
NIC's AFAIK.

Is it possible to do IPNat with only 1 interface?
I've tried some of the basic examples but my Win98 box will have none of
that. (Plus 'ipnat -l' show nothing).

Thanks,
Chris
