More follow-up:
I've noticed that my recent client has the same internal IP address as my
site. This actually posed an issue when connecting to their site.
My site was picking up my internal IP address and when connected to their
site resources could not be found because the VPN'ed resources were trying
to resolve back on my site where they could not be found.
I also run a back to back with DMZ in the middle all with private addresses.
On the internal site DHCP is just fine, however, I don't have a DHCP server
out in the DMZ. So, I decided to use the non-routable 169.x.x.x address on
the external fire wall for my list of address for incoming VPN connections
rather then DHCP.
I still have VPN issues but things are getting closer.
Thank you,
Joseph

In my experience RRAS grabs a bank of IP's from your DHCP server and uses
them for clients. This bank is usually something different than the bank
that your DHCP server gives out to it's internal clients.
For example. My internal clients all are getting ip's in a range from
10.128.5.x to 10.128.8.x
The ISA banked the range from 10.128.9.x - 10.128.10.x
Not sure how it "Knew" to do that but it did. I've never had problesm with
conflicts. Those IP's that RRAS grabs and banks should appear as "leased"
on your DHCP server.

Does the ISA VPN cache dhcp leases from an internal dhcp server? I thought I
had read somewhere that it grabs however many you have connections enabled
for. I had deactivated a scope on a dhcp server but the ISA server is still
giving out its leases.
I have restarted the RRAS server with no luck. Does anyone know the trick to
releasing these addresses?
TIA
Chris
