    Does anyone know if Linking a Sql Server - to another Sql Server (via Linked Servers) requires opening additional ports in a firewall ?

    Thanks for any help

    Need 1433, TCP open. 1434 UDP if looking for instances.

    If you have a named instance and you need to connect through a firewall, you can statically set the port for the instance. Then, when connecting from the other server, you can set the , instead of \. This means you don't have to open udp/1434.
