5.  Add

source s_sys {
        udp(ip(0.0.0.0) port(514));
};
filter f_router  { facility(local3); };
 ###ROUTER IP###
filter f_A { host("1.1.1.1"); };
filter f_B { host("2.2.2.2"); };
filter f_C { host("3.3.3.3"); };
###UNKNOWN ROUTER###
filter f_unknown { not ( filter(f_A)
                        or filter(f_B)
                        or filter(f_C) ); };
###LOG FILE LOCATIOM###
destination A { file("/var/www/netlog/A.log"  perm(0644) sync(10) ); };
destination B { file("/var/www/netlog/B.log" perm(0644) sync(20) ); };
destination C { file("/var/www/netlog/C.log" perm(0644) sync(20) ); };
destination unknown { file("/var/www/netlog/unknown.log" perm(0644) sync(10) ); };
###LOG SETTING###
log { source(s_sys); filter(f_router); filter(f_A); destination(A); };
log { source(s_sys); filter(f_router); filter(f_B); destination(B); };
log { source(s_sys); filter(f_router); filter(f_C); destination(C); };
log { source(s_sys); filter(f_router); filter(f_unknown); destination(unknown); };

6. Edit /etc/sysconfig/iptables and Add
-A RH-Firewall-1-INPUT -p udp -m udp --dport 514 -j ACCEPT

8. mkdir /var/www/netlog
9. service iptables restart & service syslog-ng restart & service httpd restart
10. chkconfig --level 3456 syslog-ng on
11. Edit /etc/logrotate.d/syslog-ng

/var/www/netlog/*.log {
    daily
    notifempty
    missingok
    copytruncate
