How can describe into service list H323 traffic? Can I decide what type of traffic make NAT or no? For H323 traffic I don't must use NAT. Help me!! [:S]
H.323 is one of the hardest protocols to get through a NAT. The NAT MUST be H.323 aware. H.323 uses up to three back chanels compared to FTP's one. But worst, the addresses and ports to use are in ASN.1 commands. Thus the NAT MUST do ASN.1 decoding.
MANY NATS cannot handle H.323. SIP will be the answer in the end.
