[syslog-ng] tcp source configuration

Hello, I'm trying to configure my syslog serveur to receive syslog message from a rsyslog client. I used something like that : *source myRemote { tcp(ip(172.25.5.1) port (69000)); }* * * Indeed, all works fine except the fact that the port i specify is never used, and it seems that a random port is chosen instead ( at least, it a tcp port ).* * Each time I change the port in configuration, another port is chosen. I checked in netstat that the port I specify is not already used, so it's another problem. Can somebody help me ? Thanks a lot :)
