[Openh323gk-developer] About Citron NAT technology

[Chih-Wei H. <cw...@li...>]

Hi,
For those who interesting in this technology,
now it is ready for testing.

Simply speaking, this technology solves the NAT problem of H.323
without any modification requirement for the NAT box
(that is, you do not need to install an proxy on NAT,
no port forwarding, etc,... are needed.)


In this figure,

       PGK -- EP1
        |
       NAT
        |
EP2 -- CGK


PGK and EP1 has public IPs, while CGK and EP2 has private IP.
(CGK *do not* have public IP, i.e., it's behind the NAT)
CGK registers with PGK as an endpoint.
EP1 registers with PGK and EP2 registers with CGK.
Note both of PGK and CGK must use the latest CVS, branch v2_0.

In PGK, remember to enable SupportNATedEndpoints.

[RoutedMode]
GKRouted=1
SupportNATedEndpoints=1

CGK is running in routed mode (proxy is *not* needed)

Now EP1 and EP2 can call to each other.

Let me know if you succeed to do the test.


I'll give a more technical explanation for it later
(if I have spare time..:p)


Cheers,
