Is your cable modem connected to a router or direct to the computer? The
reason I ask is that a while back we were trialing routers for some of our
employees and we found two models that would cause SecureClient to
re-authenticate every 30 minutes almost to the second. Both were Thomson
Speedtouch routers if memory serves. I also found a colleague who was using a
Netgear of some kind with the exact same problem.

Hi,
What's your IP address when on the internet ? I'm just wondering if your
new ISP uses nat that could break the VPN connection, if not that
perhaps they block it anyway. I'm assuming the switch from dsl to cable
involved a new supplier.

If that was the case it probably wouldn't connect at all. Have you tried any
of the connectivity enhancements like forcing UDP encapsulation?
