I have ISA2006 server installed on my office network and all the pc on the network are using SNAT. some of the users on the network have nortel vpn client to connect to corporate head office. Through ISA2006/TMG SNAT nortel vpn client fails to establish a tunnel.
The policy for ISA is set to allow all traffice from inside(internal network) to external and no other restriction is added in the policy.
nortel client version is v04_87
