Hello Jan, thanks for your answer. I think i did not describe it with enough details:
My Network is like the following: 2 dedicated Videoconferencing Systems in my LAN with a private IP (192.168.88.x) behind one Router with only one public IP Address (79.142.35.177) I have an gnugk instance installed infront of my Firewall. The dedicated systems register themselves without any Problems on the gnugk. Then I try to call a public MCU bridge with a public IP. The first system from which I call the MCU is able to connect, no matter which system I use. The second system is not able to connect, it get a "disconnect" and can't connect to the MCU. As you now, my gnugk configuration is very basic, so I think I am missing some points to make it happen that 2 systems in on LAN can connect through one public IP on a public MCU. I hope you understood my network now. Are there any config Options which I should use to make it work?

But your description sounds like you have placed your GnuGk inside your firewall / NAT and thats not a good place for it. It seems like sheer luck that one of your endpoints works. The best place for GnuGk is outside your firewall. Then all your endpoints can live on private IPs and use H.460 NAT traversal to connect to GnuGk can dial out or be called from the internet. The other option is to configure port forwarding between your router with the public IP and GnuGk. But it is much more error prone and I generally don't recommend it.
