NAT Match Host and PIX Alternative

Hi,

I need to NAT between 2 x networks matching the host element so that my host in LAN 1 is translated to the same host address in LAN 2 e.g.

192.168.1.1 NAT's to 192.168.2.1 192.168.1.2 NAT's to 192.168.2.2 192.168.1.100 NAT's to 192.168.2.100..... etc

Ordinarily I would use the NAT 'match host' command on a router but I assume I can do this on a PIX by doing something like

nat (inside, outside) 192.168.2.0 192.168.1.0 netmask 255.255.255.0

I don't have a PIX to hand to confirm that the mappings on the host portion will be identical. Anyone know off the top of their heads.

Regards

Darren
