The VPN uses the 172.27.0.0/16 network.  The VPN server, on tun0, is 
172.27.0.1.  The VPN client is 172.27.0.14.
The VPN server exists on its LAN 192.168.0.0/24 as 192.168.0.71.
The remote client has a remote LAN address of 10.4.1.140.  I'm trying to 
reach 10.4.1.150 through the VPN.

I have tcpdump - but I don't know how to use it.  Do I run it on the 
server ('cuz if I need to run on the client - I need something Windoze 
compatible).
