I have got both subnets in the LAT but I'm not using SecureNAT at the
moment, I could try this but I think it will have an effect on our VPN
connection. I have implemented a router-router VPN using two ISA servers
to connect to a remote office, removing the firewall client from the
workstations seems to compromise functionality when trying to connect to
services in the other office. However I will try this route and see how
I get on, thanks for the advice.

Do you have both subnets in the LAT?
Also; all users in both subnets will have to be secureNAT clients in
order to use ISA as a router.
BTW, ISA wasn't designed with this in mind...

Subject: [isalist] ISA server and multiple network adaptors
http://www.ISAserver.org
Hello out there,
I wonder if anyone out there can help with this problem I am currently
experiencing, this has been frustrating me for the last few days and I'm
close to giving up.
Does anybody know if there is any way I can use my ISA server as a
standard router (to route between two networks) as well as a firewall
and Internet proxy server?
The ISA server has three network interfaces:
Interface 1: Connected to Cisco Pix Firewall (ip 213.249.147.90)
Interface 2: Internal network (192.168.168.8)
Interface 3: Network to be routed to and from (192.168.3.100)
I have been trying to use the second and third adapters for allowing
users to connect across the two networks and I haven't had much success.
The ISA will see the second network card as an internal adapter but it
seems to treat the third network card as an external interface and so
applies security and packet filters to it. Is it possible to have two
internal network adapters with ISA server or will I only be able to use
the third adapter as a perimeter network? If I could find a way to treat
both cards as internal would I then be able to use standard windows 2000
routing to make connections between networks
Any help would be appreciated.
Thanks
