VPN problem - Using 2 virtual network cards?

I am using VPN (Nortel) to access corporate network. This is working
fine, but I have one problem which is not a VPC problem but how the VPN
client works.

When I use VPN I can't access any local network resources including the
host PC and my host PC can't access the guest VM (ie using networking).
Can't even ping I can of course use shared drives to access files on my
host but I want to have full local network access to/from guest.

I am neither an expert on VPN clients or networking in general. Maybe it
can be solved in some other way, but wouldn't one solution be to have
two virtual network cards. One for normal network card (bridged
networking) which is bound to the vpn client and another (probably using
NAT or local).

Could that be a solution or do you have any other suggestions?

This is *definitely not* a VPC issue at all. Nevertheless:

What it is all about is the *security* of the network you are VPN-ing
into. Your VPN client is probably working just like my Cisco VPN in
that it effectively disconnects your PC *totally* from its own network
neighborhood when the VPN tunnel is established and instead moves it
over into the remote network. Whilst the tunnel is up there will be
*no* connection between the two networks through the client PC.
I believe this is by design for secure VPN clients.

If you instead used Microsofts not-so-secure PPTP VPN protocol, then
it is possible to configure the PC such that it sees the remote
network as an *additional* network and therefore it can access both.
But corporate IT departments generally loathe this solution since it
effectively compromises their carefully protected network.
