VPN to OSX from windows machine? The environment i have setup consists of an OSX Server, running file sharing and VPN. 

The file share is accessible from the local network on both windows or OSX machines, and OSX machines have no problem connecting to the server via VPN when on a remote network. 

However, i can't seem be to able to set the VPN/File share up via a windows machine that is not on the local network, can anyone advise further as to how I would allow windows machines to connect to the osx servers file share/vpn from a remote network? 

Thanks!
Add this to your registry:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\PolicyAgent]
"AssumeUDPEncapsulationContextOnSendRule"=dword:00000002
Open secpol.msc (click start > search for secpol.msc)


Local Policies > Security Options
Network Security : LAN Manager Auth Level…
Set to: Send LM &amp; NTLMv2 - UseNTLMv2…



And


Network Security : Minimum session security… clients
uncheck "Require 128-bit encryption"


Restart PC
Create VPN Connection on Windows 7

Host Name: (server IP or yourhost.name.com)
PPP Settings : Enable LCP (only)
Type: L2TP/IPSec
Pre-shared key : yoursharedsecret
Data encryption : Optional encryption
Allow CHAO and CHAPv2


Router on server-side must allow VPN Passthrough and forward ports: 50, 51, 500, 548, 1701, 1723, 4500 to the server box. Also, do not filter anonymous internet requests, multicast or NAT Redirection but enable SPI Firewall.
