Title: RE: [FW1] Netmeeting

H.323 is a little odd when it comes to NAT. Checkpoint doesn't translate the IP address that is embedded in the data field of H.323. There for, when using NAT, H.323 will not work correctly. It will work just as you described below or you will only get up the session but no video or audio. Your only other option is to put in an H.323 gateway. Other than that, it was the way the protocol was written.

Hi Guys,

I have a PC hidden behind the firewall and static nat.
When initiate from the PC which is hidden behind the firewall.
The external PC can see my private IP. Why? I though the whole idea when
using NAT so that external PC would not be able to see my private IP.
I can use External PC to initiate the internal but not other way round.

Can someone tell me what I have done wrong?

I have followed the instruction from Checkpoint and still could not get
my Internal PC to initiate the External

Help.

PB
