netmeeting 與 msn messenger不同,它使用 H.323 protocol,運作方式複雜的多
(1) primary connection:
H.323 setup ==> tcp port 1720
audio control ==> tcp port 1731
T.120 ==> tcp port 1503
LDAP ==> tcp port 389
若要使用 gatekeeper (閘道管理員)則還有
gatekeeper Discovery ==> tcp port 1718
gatekeeper setup ==> udp port 1719
(2) secondary connection:
H.323 call control ==> tcp port 1024-65535 (隨機選擇)
H.323 影音資料流 ==> udp port 1024-65535 (隨機選擇)
如果您沒甚麼特殊需求,開放 tcp port 1720,1731,1503,389 應該就可以了
