Client 2 is on Internal NAT with a private IP, correct?
ISA is doing NAT, correct?
Please read the following:

If you are trying to create a VPN tunnel using IPsec from Client 2 on
the internal LAN which has a private IP address, through the ISA which
is doing NAT, to the Cisco (client 1), unless someone can correct me, it
will not work.
This is a restriction of NAT and IPsec.
Why do you need a VPN tunnel from an internal client to the router?

I know the following information is a bit vague but this is all I have
(so
far)
Server1 (CISCO FIREWALL).....Client1
|
|
|
Server2 (ISA).....PC2
Client2 has got Cisco VPN Dialer setup with:
Enable Transparent Tunnelling (Allow IPSec over UDP (NAT/PAT)
I have been told the following information:
Setup UDP Port 500 Protocol 47
I have tried this but to no avail...And am getting presurised in getting
it working (yesterday)
Please could someone advise what I require opening/setting on the ISA
firewall? (I will answer as many questions as I can to help)
Again, I know it is not much to go on but all assistance is much
appreciated.
Regards,
AMIT.....
