I, too, am working on “HowTo” documents for host-LAN and LAN-LAN VPN networking. For now, I would like to add an important step. I had an issue where the VPN would suddenly stop working during high-speed transfers. I am using Windows XP on a public network to connect to a private network behind Zeroshell:
Windows XP <---> Zeroshell <--> private network
Here are two important registry entries:
[HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesTcpipParameters]
“EnablePMTUDiscovery”=dword:00000001
“EnablePMTUBHDetect”=dword:00000001
These settings are discussed at

and
http://www.microsoft.com/technet/prodtechnol/windows2000serv/reskit/regentry/58751.mspx?mfr=true
respectively.
