maybe the Cisco client is disabling IP-Forwarding on the Windows machine,
I've seen this with a similar client software from Checkpoint (it refuses
the installation if IP-Fowarding is enabled).

One of my customers is using such client software from cisco, but there
were no problems, I just had to open UDP port 500 (isakmp), but this
customer has a leased line with a router and no PPTP/PPPoE connection must
be established when connecting to the internet.

sorry,
bye,
