Cisco 1721 and Nortel VPN Client

[jabIsOnTheJob]

Hello:

I have a 1721 in a NAT configuration for 20+ work stations and 5 servers on an NT domain:

ip nat pool net-1 222.222.222.112 222.222.222.127 netmask 255.255.255.224
ip nat inside source list 1 pool net-1 overload
ip nat inside source static 172.16.2.1 222.222.222.100
ip nat inside source static 172.16.2.27 222.222.222.101
ip nat inside source static 172.16.2.26 222.222.222.102
ip nat inside source static 172.16.2.45 222.222.222.103
ip nat inside source static 172.16.2.47 222.222.222.104
ip classless
ip route 0.0.0.0 0.0.0.0 222.222.222.97

One of my firm's clients would like for one or more of our Windows 2000 workstations to VPN into their network using the Nortel Extranet client. I can't for the life of me get the VPN to function correctly.

It would seem to me, that using a static NAT for the workstation should work but it doesn't. The VPN connection seems to progress to a certain stage, and then I get a 'Bannersock' error.

Can anybody help me - it would be most appreciated.

Thank you
