[VPN] Local network neighborhood gone when VPN connects

What your seeing is "by design".  This is to prevent some other system to gain access to your office network through your VPN.  The concept is called "split tunneling" and by default it is disabled.  Check through your client config to see if there is an option "allow split tunneling".

Hi Nate,

These are notes that I copied ages ago from someone's post  ... they
don't say how to change it, but at least they confirm that you are not
alone.  Maybe someone else can shed more light on why.

****.
The Cisco VPN client overides the home LAN settings from home once the
VPN session has been established.  Your home network becomes invisible
to the rest of your home connected computers and all of the office LAN
is visable to only the PC with the VPN client running.  I use a
Netgear router connected to the cable modem and DHCP on the home
network.

I have never gotten an NT login screen through the VPN.  My boss does
when he is at home, but I don't.  It might be in how it is setup by
our IT group. [Depends on whether you already logged in to local PC]
No big deal, I just have a local batch file that maps
the office network drive letters.  I just make the VPN connection
thourgh the cable modem and run the batch file and it is just like
having a NT profile on the office LAN.
