Security

Prior to using HEAnet's videoconferencing service, there are a number of security issues involved in allowing H.323 conferencing.
 
The following ports are used in H.323 conferencing:
 
H.323 Ports (open in both directions)
 
Function Port Type
HTTP Interface 80 TCP
Gatekeeper discovery 1718 TCP
Gatekeeper RAS 1719 TCP
Q.931 Call Setup 1720 TCP
Audio Call Control 1731 TCP
H.245 Control Channel 1024-65535 TCP
RTP (Video/Audio) 1024-65535 UDP
H.235 secure signaling 1300 TCP
T.120 1503 TCP
Because H.323 uses dynamically assigned ports it is difficult to control. Some solutions to overcome this are as follows:
 
  • Open the ports listed above on your institutions firewall
  • Use H.323 aware firewalls, e.g. Cisco Secure IS, Cisco PIX, Checkpoint FW-1, Netscreen
  • Use a separate network for H.323 (H.323 DMZ)
