[vpn-help] VPN established, no traffic can pass through.

[Michael Wade]

VPN client 2.2.0 beta 2
Win 7 SP1
Router: NetVanta 3448
Firmware: 17.04.01.00.E

We have had trouble free operation for several years and have a number
of Fujitsu tablets running Window 7 64 bit SP1. The tablets have been
running successfully for 3 or 4 months and now one of them has developed
an issue that has us stumped. 

We can establish the VPN, but when we try to ping the VPN gateway
(172.20.4.1) we get a message from the local client gateway (10.100.1.x)
that the destination host is unreachable. Pings to VPN side IP's fail.

We've tried ripping out all of the network adapters, clearing the
routes, reinstalling the software, but can't get anywhere with it. Any
help would be appreciated.
