Synology has added L2TP/IPSec as an option for a VPN.
I’ve never been able to get it to work on a Windows client until today.
Ports Required:
- IPSec – UPD 500
- IPSec NAT Traversal – UDP 4500
- L2TP – UDP 1701
Fix on Windows clients – http://support.microsoft.com/kb/926179
- For Win7 and Win8 Machines
- HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesPolicyAgent
- New DWORD (32-bit) – AssumeUDPEncapsulationContextOnSendRule
- Set the Value Data to 2
Update:
Using OpenVPN with port 443, for easier access: http://forum.synology.com/enu/viewtopic.php?t=45545#p215354
