Incoming ports

FTP - TCP:21 + TCP ephemeral (i.e. dynamic rather than fixed) ports used for passive mode
HTTP - TCP:80
H.323 - TCP:1720 + TCP ephemeral ports for incoming calls
RTSP - TCP:554
Windows Media Player streaming - TCP:1755

Outgoing H.323 calls involve TCP connections from TCP ephemeral ports to TCP:1720 + a TCP ephemeral port

Outgoing SIP TCP calls involve connections from TCP ephemeral ports to TCP:5060

Outgoing SNMP traps are sent from UDP ephemeral ports to port 162

Media (including audio, video and FECC messages) is UDP from ephemeral ports to ephemeral ports.

The Codian products allocate ephemeral ports in the range 49152 to 65535. It is possible to change the ports on which Codian products receive and establish connections. For instance, by default Codian products listen for H.323 calls to port 1720 and web browser connections to port 80 but these can be changed. Go to Network > Services.

Outgoing ports
RAS - UDP:2222 for gatekeeper client messages and UDP:1719 for the built-in gatekeeper server (if enabled)
