VPN Sierra Server error L2TP VPN server did not respond
Hello to all
I use Sierra server 10.12.6 and vpn service to connect my Mac to my compagny
But since somes days I have an error
Macbook pro (used in 10.12.6 too) say "L2TP VPN server did not respond. Try to connect again. If the problem persists, check the settings and contact the administrator" used in 10.12.6
This error appear only in external
If I use internal ip adresse it s works and connection is OK
The problem is same with local user or OD user
On router UDP ports are open to my server 500 / 1701 and 4500 (all in UDP)
