Wenn man eine VPN-L2TP-Verbindung zu einem OSX-Server unter Windows 7 herstellen will, so funktioniert diese nicht standardmäßig. Man muß hier ein paar Anpassungen machen:
Here are the steps:
1. Add this to your registry:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\PolicyAgent]
„AssumeUDPEncapsulationContextOnSendRule“=dword:00000002
2. Open secpol.msc (click start > search for secpol.msc)
– Local Policies > Security Options
– Network Security : LAN Manager Auth Level…
– Set to: Send LM & NTLMv2 – UseNTLMv2…
And
– Network Security : Minimum session security… clients
– uncheck „Require 128-bit encryption“
3. Restart PC
4. 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
5. 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.
I now can successfully VPN from Windows 7 to MAC OSX Lion Server! YAY!
