My network Setup :
SBC DSL - Linksys Router - SBS external Nic - SBS Internal NIc
ISA Firewall
INBOUND PPTP VPN works fine.
I want to let local XP computer connect using Netscreen Remote VPN client to a remote VPN server. Netscreen client is IPSec based.
I have setup protocol definitions in ISA firewall for UDP 500 and UDP 4500 outbound. And created a rule that allows these two protocols.
But no VPN connection. The Administrator on the other end does not see any connection from my side in his logs. I dnt see anything in my logs either. So I am guessing it has something to do with ISA setup - in particular I have to set up that XP workstation as SecureNAT client.
How do I do this?
Here is my IPConfig /all on the server and the XP workstation:

What should the Gateway be for the XP to make it a Secure NAT client - 192.168.16.2 or 192.168.1.100 ?
Also do I need to make any changes in ISA to make this a SecureNAT client
Thanks
