Or, slam another FE port into that Cisco and then let it handle all the routing for you. Just advertise another subnet to the two existing ones and BAM!...you got game.... Then just pump all the traffic up your new pipe to the ISA, al la: Internet ...| ..isa ...| ...| <---(new subnet) ...| ..2600----(subnet1) ...| ...| (Subnet2) Default gateways on subnet1 and subnet2 stay the same so there just about zero config and all your existing ACL's on the router would still be valid.... All the coolness of an ISA protecting you, and a dedicated device to do all your routing for you. Best of all worlds.... -----Original Message----- From: Dan Johnson [mailto:djohnson@xxxxxxxxxxxxxxx] Sent: Wednesday, September 29, 2004 2:52 PM To: [ISAserver.org Discussion List] Subject: [isalist] RE: ISA Important Question http://www.ISAserver.org Troy, Thank you for your help. I have installed ISA at a previous job but it only involved one network. Now I am working were there is 2. So I just wanted to make sure this works before I purchase anything.

Or have the ISA on both networks and set up routing on that and have it be the default gateway for everything..... -----Original Message----- From: Dan Johnson [mailto:djohnson@xxxxxxxxxxxxxxx] Sent: Wednesday, September 29, 2004 2:14 PM To: [ISAserver.org Discussion List] Subject: [isalist] RE: ISA Important Question http://www.ISAserver.org Yes, both networks go through a Cisco 2600 Router that has dual ethernet ports -----Original Message----- From: Troy Radtke [mailto:TRadtke@xxxxxxxxxxxx] Sent: Wednesday, September 29, 2004 1:15 PM To: [ISAserver.org Discussion List] Subject: [isalist] RE: ISA Important Question http://www.ISAserver.org Are both networks routed? -----Original Message----- From: Dan Johnson [mailto:djohnson@xxxxxxxxx] Sent: Wednesday, September 29, 2004 1:59 PM To: [ISAserver.org Discussion List] Subject: [isalist] ISA Important Question http://www.ISAserver.org I am looking to install ISA but have one question.
