reconfigure the IP address of RASaddress behind a NAT

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



MY QUESTION:

Does anyone know how to configure the gateway so that the IP address in the RAS messages contain an IP address that I specify myself (short of recompiling the code that is!).

 

 

MORE DETAILS:

Here is my configuration:

 

 ‘MACHINE-A’      ‘NAT-1’                    ‘NAT-2’       ‘Gatekeeper’

 192.168.1.100----192.168.1.5                192.168.1.1----192.168.1.19

                  80.238.38.133---INTERNET---213.3.7.56

                     

Machine-A recevies everything sent to the public IP of NAT-1.

The Gatekeeper receives everything sent to the public IP of NAT-2.

When Machine-A tries to register on the Gatekeeper, the Gatekeeper sends back a RAS message with the payload containing the private IP address of 192.168.1.19 instead of the public address of 213.3.7.56. This provokes Machine-A (once it receives the packet) to make a local ARQ for 192.168.1.19 (which fails of course). I’m hoping that if I can convince the Gatekeeper to use a payload containing 213.3.7.56 then the Machine-A registration with the Gatekeeper will succeed.

 

Note: If I don’t use the gatekeeper, I *can* successfully establish h.323 ip-ip connections from machine-A to 192.168.1.19 and/or the other way. But I want to use the gatekeeper!

 

Note2: my h.323 client is OhPhone.
