My Network is configured like Edge Firewall, 2 Nics 1 internal and 1 external. I have a new Isp with different Ip and Router. I can install a third nic. How i can configure Isa Server to work with 2 Isp.
I need to send traffic over tcp port 80,21,22,443 With Isp1, and Tcp por 500, and others tcp ports over Isp2.

Thanks

Short answer is you can't with just ISA

You can get an add-on product called RainConnect from Rainfinity that will get you that functionalility. This is a very expensive peice of software...

I am using a program called Intergate (www.vicomsoft.com) on another computer to have two diferrent ISP and combine the bandwidth of both of them. The ISA has a gateway to the Intergate computer and works perfectly. And it is much less expensive that Rainconnect, but you have to have another computer (you cannot install it on the ISA computer). You do not need to have many licenses as you have only one "user" that goes out through Integate (one is enough!)

I have the same issue. I have 2 xDSL connections that I need to use.
Is it feasable to stick another ISA server in a DMZ and route web traffic through to that server, and leave mail services routing through the existing ISA server??

Many Thanks

James

I was looking at a similar situation except for fail-over not pooling connections.

In a 3NIC box, Nic1 to the LAN, Nic2 to ISP1 and Nic3 to ISP2, can't Windows Server or ISA sever to failover to ISP2 if ISP1 is down?

Wouldn't that just be a matter of routes and cost on the server? 2nd ISP route at a higher cost for failover connectivity?

Hi I also have the same problem, three ISPs and I want to direct the traffic from ISA Intern to the various ISP depending on IP range and/or requested traffic (http, smtp etc.)

I'm am trying to find prices for Rainconnect but that seems rather difficult, does anyone know any alternativ? The other suggested Software probably doesn't work as any server after the ISA will not be able to split the traffic intelligently...
