There was about 56 kilobytes of debug info following Setup. With overhead, it probably exceeded the TCP window size, so some of that text had to be sent over the relatively slow DSL uplink and acknowledged by the SSH client, before GnuGK could proceed. > The company uses HW firewall (NAT) so I can't use my server instead of > it and another public IP is not available to me. I maybe can put GnuGK > machine into DMZ zone but this is insecure - I don't want to do that. IMO, DMZ won't help -- the GK would still need to put its public address in various packets. So you'll probably need to find and fix the problem with NetworkInterfaces. I'm puzzled why your simple case is not working, since many users have GK behind NAT and do the same thing. I'll be traveling for the next few days, so may not be able to respond. --Stewart ------------------------------------------------------- This SF.Net email is sponsored by: InterSystems CACHE FREE OODBMS DOWNLOAD - A multidimensional database that combines robust object and relational technologies, making it a perfect match for Java, C++,COM, XML, ODBC and JDBC. www.intersystems.com/match8 _______________________________________________________ List: Openh323gk-users@xxxxxxxxxxxxxxxxxxxxx Archive: http://sourceforge.net/mailarchive/forum.php?forum_id=8549 Homepage: http://www.gnugk.org/
