[isalist] RE: Isa2k4 and IPSec VPN to Cisco RouterCool, cheers Dan.
My setup is with 1 internal nic and i have done all the route adds already, so
looks like mine was set correctly. The only thing i need to resolve is pointing
the clients to the right point in the network for the default gateway. I'll try
this tomorrow on some test machines.
Ok, the subnet thing is clear also.
Thanks again Dan
Paul

I guess it all depends on how you have your networks setup (which is what
prompted my other discussion). Sorry, I had deleted all the previous messages,
so I don't remember the details.
To summarize it, If you have one internal network NIC in the ISA computer,
and all of your subnets are behind it, you need to add those IP ranges into the
ISA Network Configurations, and add a ROUTE command to make sure those ranges
are going to the right NIC. Or, possibly, increase the subnet mask to make the
subnets included. Okay, there is a "little more" to it than that, but that
will summarize it.
If you have more than one internal network NIC in your ISA computer, you have
to do things differently. That is where I haven't found any articles
referencing that setup, I had to do most of it trail and error.
Which one do ya got?
The "Firewall Policy" part is only if you want to have different settings for
different subnets. If you want all of your Internal networks to use the same
settings, then don't worry about it.

ok guys i thought i cracked it but now i'm slightly confused since reading
Clints 'Network behind a network' document and also visited the discussion.
In the document it states :-
<-snip->
Can i now presume that i add my physically connected subnet to the 'Internal'
network as well as my other subnets to the 'Internal' network, but i also
create Subnet Objects for my other subnets and modify the Firewall Policy
Access Rules to reflect these changes ?
Sorry for being a dumb a$$
Paul
