Come to think about it, is that not what a dial up connection is
anyway???

Hi Mark,
Your ISP will allow you to create a VPN link just to download mail?
Wow!
Thanks!

Subject: [isalist] Howto make ISA server a VPN client
Hi folks,
I am currently evaluating a scenario in which an Exchange Server
behind ISA connects to the ISP's mail server via VPN, thus elimiating
the need for a static IP address. Now I'm facing some problems of
understanding which you can hopefully help me get rid of.
- Do I have to make ISA or the Exchange Server the VPN client?
- ISA does not support L2TP-tunneling, does it? I would rather
not use PPTP, as does the provider
- So, do I have to set up a static route to the ISP mail server
on the ISA machine? With RAS? (btw I already tried that but the route
seems to work only on ISA itself? - of course it didn't work but I
wanted to see what happens :-)
- Can this route point to an interface that I created with the
VPN wizard of RAS?
- Or is this configuration completely impossible?
- And finally if it *is* possible, what kind of packet filters
to I have to set within ISA? Can I use Tom's article on ISA to RAS
connections as a guideline or is there some substantial difference
between a gateway-to-gateway configuration and my idea of ISA being a
"client" for that matter?
As always, thanks for listening!
Mark
