Thanks Tom, for your work.
I''m headed out to finish a transition at one of my clients,
I''ve
wanted to create a particular setup which is fairly non standard. So
this is a general question (So I know whether to post more info and the
configs). I''m assuming this is a yes or no question.
I have two RFC 1918 subnets:
eth0 192.168.0.0
eth3 192.168.1.0
And two ISPs:
eth1 <ISP1>
eth2 <ISP2>
I want to accomplish the following with NAT:
192.168.0.0 --> <ISP1>
192.168.1.0 --> <ISP2>
Is this possible? No balancing, just straight NAT.

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 \ teastep@shorewall.net PGP Public Key \ https://lists.shorewall.net/teastep.pgp.key ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
