I have an IPSEC VPN through my pfSense to my clients local network via their SonicWall.
I can connect to any authorized server or share on the local subnet, and an MS SQL instance running on a single server.
I can NOT connect to the 2-server cluster on the same subnet. Permissions, logins and users are the same for the cluster and the single instance. (they were copied) Everyone on the local subnet connects with no problem.
It is configured for remote connections, named pipes, dynamic TCP/IP, just as the single server was.
I don't know what to try next. Any ideas?
