Jan, If GnuGK is not on a public IP, but in a router's DMZ, therefore no firewall rules, can it still act as a NAT traversal, even if it is behind a NAT * using H.460.17/18/19 * using Pacphone P2PNAT * using Ekiga ? The assumption is that GnuGK has a fixed public IP address or a dynamic DNS service, so that it knows its public IP as well as its LAN subnet. Or does GnuGK have an *absolute* necessity to be on a public IP to offer NAT traversal for its own internal LAN and for the external Inet cloud?
