RE: [FW1] Doing NAT to more than one public network



You probably mean that CP only supports one external interface for licensing
purposes.  This is true.  FW-1/VPN-1 will be more than happy to deal with as
many "external" interfaces your network topology supports if you have an
unlimited license (I believe there is a  real limit though and am
exaggerating to prove a point).  Remove your $FWDIR/conf/external.if file
iff you have an unlimited license, bounce the FW and then see how much it
cares about only one external interface...it doesn't.

FW-1 only supports ONE external interface, regardless of license used.
However, you should be able to NAT as many public addresses as you want.
