configuring syslog-ng in relay mode

[badri.avg]

Hi,

I am having issues in configuring syslog-ng in relay mode. This is my setup

syslog-ng client -> syslog-ng relay -> syslog-ng server
(10.1.2.108)           (10.1.2.1)               (10.1.2.10)

and this is my syslog-ng.conf file on syslog-ng relay machine

options {
                mark_freq(30);
                };
               
                source s_local { unix-stream("/dev/log"); internal(); };
                source s_network { syslog(transport(tcp))};
               
                destination d_syslog_tcp {
                syslog("10.1.2.10" transport("tcp") port(19999)
                );
                };
               
                log { source(s_local); source(s_network);
                      destination(d_syslog_tcp); };

From the above config I can understand that server listens on 19999 port. But on which port relay listens..? My client needs port number also to send the logs to relay which in turn will be sent to server. The default port 514 is closed on relay.

It will default to the "syslog" service - which is UDP port 514.
