[Openvpn-users] Re: Bridged LANS behind firewalls

[Matthew Mastracci <matt@xxxxxxxxxx>]

Not sure if you've considered it, but you might want to use separate 
subnets with something like WINS for name resolution across the 
subnets.  It's far more efficient than bridging, unless you're using 
protocols that require broadcasts to work (ie: Rendezvous with iTunes, 
etc.).  You can use SMB across a subnet, as long as you know the windows 
name <-> IP address mapping (which is what WINS provides).
