Does not work? (Show us.)

Try something like:
ipmasqadm portfw -a -P tcp -L 192.168.0.1 25 -R 192.168.0.2 25
Your remote interface needs to listen on the original IP too.
You do need to have your kernel built with the appropriate masquerading
options. (Read your ipmasqadm manual page and do "ipmasqadm portfw
-h" for help.)
