Rsyslog doesn't send logs to logstash server on port

I have two rsyslog-client and rsyslog-server. When I tried to "logger -p local1.notice SOMETHING" I don't see any information on server from one client, but from another I see logstash output. I have copied rsyslog.conf, it's identical on these two servers. What's wrong? When I test the connection via telnet x.x.x.x 10514 from problem server, telnet connection is ok and I see tcpdump logs. And when I change tcp listen logstash port to 514 all works properly. When I do logger -p on problem client I don't see anything in tcpdump -i any on it. But if I do the same thing on "OK" client I see outside traffic via tcpdump to port 10514 (or something different). When I change logstash port to 514 problem solved.
