GPRS Hardware compatibility with VPN Client - Sierra AirCard 750

Hello,

Prior to testing the below configuration, a Nokia GPRS Phone connected via bluetooth to the Client works fine using the same VPN Client Connection Entry

Client OS = Windows 2000, with latest Service Pack 3

Client VPN Version = 4.0.2 (A)

VPNC 3060 version = 4.0

Client Hardware = Sierra AirCard 750 (using latest win2k drivers)

It has been noticed that when this card connects to GPRS, its creates a new "Local Area Network" connection which it passes traffic through (private address is assigned by GPRS-provider (o2), therefore IPSEC thru NAT has been accounted for) When the VPN connection is attempted, the following log is displayed on the VPNc3060

This occurs AFTER user authentication has been (correctly) entered and authenticated.

Any ideas why this doesn't establish a VPN tunnel ??

I notice that all the GPRS client connections use IPSEC over TCP. Have you had a chance to test IPSEC over UDP or NAT-T with these connections?
