Jay,
 
Thanks for the response.  Having never set up proxy before my question is,
do I need to set up something on the ISA server before I point the client to
it.  If so, which one the perimeter server or the DMZ/LAN server.
 
Thanks,
Brian

Brian, 
 
   Your IP stack does take on a new identity when you are VPN'd in. so once
connected, could it be that your Browser then needs to be pointed at the ISA
server for proxy service?? thats what I have to do on mine.

Many thanks to the contributors to this list and to ISAServer.org. 

I have set up a lab to simulate an enterprise network with back to back ISA
servers.  After establishing a VPN tunnel into the network the client can no
longer access the Internet.  When I do trace route to any site the the
astericks come back on the first hop.  If I disconnect the VPN connections
all is well again.  I am using PPTP as I have not set up CertSrv yet.

Can anyone explain this behavior?  Does the IP stack lock down to point only
to the ISA server to protect from the client being hacked and an intruder
gaining an autenticated path to the LAN?

Thanks,
