So I’ve got Synology DS1515+ to replace the Lenovo drive since late 2015. And the server has been running fine. Here are a few tips for things to work correctly:
1. VPN L2TP connection requires manual registry editing:
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_MACHINE –> SYSTEM -> CurrentControlSet –> Services –> PolicyAgent
- New DWORD (32-bit) – AssumeUDPEncapsulationContextOnSendRule
- Set the Value Data to 2
