IP redirect?

[Morgan Read <mstuff@read.org.nz>]

Hi Folks

To redirect lan traffic addressed to the wan IP (e.g.) 123.456.789.012
to the lan IP address 192.168.1.123, I'm using the following:
$ iptables -t nat -I PREROUTING 1 -d 123.456.789.012 -j DNAT
--to-destination 192.168.1.123

But, all internal traffic seems to get lost - 18 months ago when I last
did this, traffic to 123.456.789.012 seemed to hit 192.168.1.123 and
come back without problem.

I've added the following, with some interesting results:
$ iptables -t nat -I POSTROUTING 1 -s 192.168.1.40 -j SNAT --to-source
58.28.20.69

Now, the traffic from the specific lan IP 192.168.1.123 does seem to be
redirected correctly and come back to itself.  But still, all other lan
traffic seems to get lost.

Any ideas what's happening, where I'm getting lost?

Regards,
Morgan.
