Just an update. I was trying to get this router working with linux.
It connected and authenticated ok, but then no traffic.

Ping www.bbc.co.uk network unreachable. I've installed the latest
CISCO VPN client:-

-rw-r--r-- 1 root root 9741824 Nov 28 11:29 vpnclient-win-msi-4.0.3.A-k9.exe

on a windows 2k machine and it works with this router (the router
is not bad). I can't get internet sharing working yet, so I can use
it as a gateway for my linux machines.

This router is actually running linux GPL'd code (which I applaud).

I just wish that CISCO would stop messing around with the 1001 frivolous
Windows bugs they are working on, and just get the core functionality
working for linux IBM machines trying to do real work.
