That is to so, you *must* use multi-ISP and you must arrange *using routing* for 192.168.0.0 to be routed out of ISP1 and 192.168.1.0 to be routed out of ISP2. I would use entries in /etc/shorewall/route_rules to do that. You use NAT (entries in /etc/shorewall/masq) to cause the source IP address to be re-written -- *that is all that NAT does -- it does not route packets anywhere*. -Tom -- Tom Eastep \ Nothing is foolproof to a sufficiently talented fool Shoreline, \ http://shorewall.net Washington USA \ [EMAIL PROTECTED] PGP Public Key \ https://lists.shorewall.net/teastep.pgp.key
