Hi Avishay
I have not terminated my VPN at the Ix and established a secondary VPN
through to the ISA. I understand that it would be more secure but I just
haven't had the time to explore that avenue yet..

Have you tried to implement your VPN connections to first connect to the PIX
with Cisco VPN Client and then to make a second VPN connection to the ISA
server? That way you suppose to have your VPN connection more secure. I've
read this implementation on one of Thomas articles but never tried it. Did
you?
Thanks,

Hi Avishay
Well, I've only just got my VPN to work in the last month, but that was more
to problems with my ISA config than anything else.
As for allowing a VPN connection through to the ISA Firewall, I have the
following rules in my access-list:
access-list acl_outside permit tcp any host <ISA's external IP> eq 1723
access-list acl_outside permit udp any host <ISA's external IP> eq 1723
access-list acl_outside permit gre any host <ISA's external IP>
This should allow all VPN connections to reach your ISA Server and then be
validated by RRAS and then everything should be just fine!!!
Cheers
William R.
