Sql Server Firewall Problems
Hi experts,
I am having a problem with Sql Server 2014 and the windows firewall.
The server is under the domain. In the firewall the port 1433 TCP and 1434 UDP are opened but I cannot connect to the server from remote.
If I disable the firewall for the domain network then I am able to connect to the server.
In any case, even with the firewall off, I can only connect using: servername\sqlinstance and not using the ip address of the server.
I doubled checked that TCP/IP is enabled in the SQL configuration and the port is 1433.
Basically with firewall on I cannot connect, with firewall off I can. The rule is set to open 1433 on private, domain and public.
Any idea what can be wrong?
