Thanks for taking the time to answer my questions. Tamas suggests the portfw module which seems to make sense. I thought that was what "ipchains -A forward" did but obviously it is a little different.
"ipmasqadm portfw" gives me the following syntax. Usage: portfw -a -P PROTO -L LADDR LPORT -R RADDR RPORT [-p PREF] Does xADDR need the netmask like IPCHAINS ? (eg. a.b.c.d/32 or a.b.c.d/255.255.255.0) Can xPORT be a port range (eg. 1000:1100) ? I assume I can redirect mail from a.b.c.d:25 to 192.168.0.5:25 with the following command. "ipmasqadm portfw -a P tcp -L a.b.c.d 25 -R 192.168.0.5 25" Is this correct ? Do I need to put this in a /etc/ipmasq/rules/.rul file somewhere (where ?) or is the /etc/ipmasq/modules file the place for it ? Will an entry of "portfw -a P tcp -L a.b.c.d 25 -R 192.168.0.5 25" in the modules file do the trick ?
