RE: RE: Strange VPN Problem

Sam, 

Try disabling keepalives in the Nortel client (options, disable keepalives).
I've seen this before and it helps most of the time.  Usually I see the
keepalives failing in a NAT environment (i.e. behind a broadband connection
with a NAT router).  It's also possible that BlackIce is blocking the
keepalives in your case.  The only functionality you're breaking by
disabling the keepalives is the automatic failover (I think...).

Hope that helps,

Bill

Hi All,

Thank for your reply. Its Dell Laptop (C610 Model) with 3com ethernet card
its not wireless... 

Operating System:Win2k professional with SP4. (Formatted and Reinstalled).
The user connects thru Fiberlink Dialer. The COntivity VPN client version
being used is 4.65.18. BlackIce Firewall is also present.

Please help me in getting to the root of the problem.

Thanx in Advance,

Sam
