Jan, I've done a tcpdump on the linux NAT box (sitting between my HDX [on LAN] and GnuGK [on internet]). You'll find attached the tcpdump filtered file...
What i can see is the following : - packet 1 : SCI is sent by Gnugk to NAT (guid = e05f75dc-6b77-11e4-b8d2-b73ea4855d77) - packet 2 : SCI is translated by NAT to HDX => only IP/ports fields in headers are changed, all right - packet 5 : SCR is sent by HDX to Gnugk => seams ok to me - packet 6 : SCR is translated by NAT to Gnugk => only IP/ports fields in headers are changed, all right - packet 3/4 : TCP SYN from HDX to gnugk:1720 is opened - packet 7/8 : TCP SYN ACK from gnugk to HDX - packet 9/10 : TCP ACK from HDX to gnugk - packet 11/12 : tcp window update (ignore that) - packet 13/14 : HDX sends a H225 facility undefined (guid = e05f75dc-6b77-11e4-b8d2-b73ea4855d77) After 5 seconds, without answer from gnugk, the HDX shuts the TCP stream (TCP RST). I'm not an expert of H323 nor H460, but i think gnugk should handles the "H225 facility undefined" and its guid to relate the TCP 1720 new session with its SCI/SCR negociation. Am i wrong with that analysis ?
