[plug] OpenVPN/CiscoVPN

[W.Kenworthy]

The afs question running at the moment reminded me of a problem I have
that someone might be able to shed light on:

I have a wireless network (using wpa_psk) running Openvpn (routed) to my
gateway which gives filtered access to my internal network and Internet
connection.  This works well.

However, I also need to run CiscoVPN at times (before anyone mentions
it, vpnc is not an alternative - it doesn't implement some of the
required options, otherwise I would be using it instead!) the other end
of which surfaces inside the network at my workplace.  However, CiscoVPN
wont connect through OpenVPN.  I know tunnelling a tunnel is not going
to guarantee good performance, but I would like to get this working as
some services are only available to local IP (to the network) IP numbers
as well as the security advantages of tunnelling through the Internet,
and not just the wireless connection.

I suspect that the problem lies with Cisco's weird way of manipulating
the linux IP stack.
