Hi All,

Just a few questions, wondering if anyone could answer them.

1. Can Exchange server traffic to limited to specific range of port?
2. Is there a recommended range of ports by Microsoft to lock Exchange
into?
3. If #2 is no, then how many ports are needed by Exchange (1, 10,
50?). Pick a high range ports say from (62,520+) to lock Exchange into.

Connections from client to server, and vice versa, use RPC. RPC used
to use a range of about 4000 ports. But with the advent of servers
supporting more users that range has expanded to pretty much all of
the "high ports".
