Can you forward me chapter 4? ;-)
I'll check out that section of the help file.

Hi Rob,
Is this the "network within a network scenario" discussed in the help
file? If so, I've got a big section on this issue in chapter 4 of the
book. A lot of people are running into this problem and its sort of
interesting once you bring the Firewall client into the mix :-))

Subject: [isalist] Is this the right way to add these "internal"
networks
http://www.ISAserver.org
Good morning--
My network consists of one main network (172.17.200.0) which is
connected to a bunch of remote networks (192.168.x.x) through VPNs
maintained by IPCop firewalls. The IPCop (freeware) firewalls all VPN
back to the home office, here, to another IPCop firewall which is on the
172.17.200.0 network.
On my previous firewalls (ISA 2000 and something called
WinRoutePro) all I had to do was create static routes to a given
network, indicating that the internal IPCop firewall should be the
gateway for these sites and voila, traffic flowed. After struggling with
this on ISA 2004 for a while this morning I've come up with two
additional necessary steps: 1. I have to add the various 192.168.x.x
networks to the Internal network; and 2. To ping or RDP to those remote
networks I have to create a firewall access rule that allows pinging and
RDPing from the Internal Network to All Protected Networks. (I suppose
I'll have to set up similar rules for the other traffic, such as SMTP
and HTTP, that goes between the home site and the remote sites?)
Is this the "right" way to do this? Is there a better, more
secure way?
Thanks,
Rob
