[syslog-ng]Logserver doesn't receving remote logs

[Viper sec]

Hey ,
I have a central logserver with syslog-ng installed and configured
(see above syslog-ng.conf), some clients (in conf just remotehost5)
send (514/udp) their logs to this logserver; but logserver isn't
receiving these logs. When I try to use local system logs, it's ok,
create the log files, but with remote host doesn't.
I have created /var/log/HOSTS/{nameserver}, and clients, that use
syslog has in syslog.conf *.warning        @logserver (/etc/hosts is
ok).
remotehost5 is pinging logserver.

Anybody has any ideia about it? (thanks too much)
