I have implemented always on availability group architecture with 2 nodes,
My application server is in different (DMZ) zone and DB server(With always on) is in different zone,
i have to connect DB server from application server with listener name,( i have configured listener),
i need to open port 1433 for which all nodes? i have already open port 1433 for primary and secondary node,
do i need to have port open for listener also along with the nodes?
