Hi Jay:

 

I was looking around my "database" of messages in the ISA Server List,
working around the issue of configuring multiple subnets in the external
interface of an ISA Server 2000; so that I can route all traffic to one
network destination by one ISP and all the other traffic to the other ISP.
So I found this answer of you. But I have a doubt about this answer. You
said: " Add a route on your ISA server for only the 222.222.222.0 network."
I need to know: Where to add this route? Windows 2000 routing table?

 

Thanks in advance

Lic. Alexey Fernandez Suarez.

They're wrong.  It's actually pretty easy to do.

 

If I understand you correctly, all traffic should go through one ISP, except
that traffic destined for x.y.z.0 network.  This might be useful if you
wanted to dedicate an entire ISP bandwidth to a private remote office vpn
for example.

 

Join both ISP networks and your external nic into a switch.

Add a second IP address to your external nic.

Leave the default gateway on the primary IP.

Add a route on your ISA server for only the 222.222.222.0 network.

 

 

We've had this configuration with a failover script for 2 years.  Actually
with 5 remote offices vpn'd to external firewalls.

 ISA does not support more than one external interface. You would need 

 a

3rd

 party product for that.

  G´day all,

 

  I work with ISA as NAT in my network and I have two external 

  interface

for

  internet.

 

  I´d like to have some help here:

  I need to connect to an especific network through only one of my 

  links. For example: Every time I access the network 222.222.222.0 

  255.255.255.0, it should

be

  made through NEC2. And the access for any other network BUT

222.222.222.0

  255.255.255.0, should be made through NEC1.

 

  Please, can somebody send me an article or site related to this 

  subject? It´s very important!

 

  Regards,

  Fabricio
