[h323plus] H323plus has native NAT support with GnuGK

Guys

Just a quick note I have committed GnuGk Nat support into the H323plus CVS. This means that the library will be able to natively traverse NAT when registered with GnuGk. There is no special code changes required as the support has been integrated directly into the library.

The only requirement is that you enable supporting nated endpoints in GnuGk. [RoutedMode] SupportNatedEndpoints=1

To work GnuGk needs to be on a public IP or configured to work behind a NAT (There is an example nat.ini in the /etc directory)

Details of GnuGk Nat Traversal can be found here http://www.gnugk.org/nat-traversal.html

Happy New Year
