That's it. It is iptables. The moment I stopped iptables I see the syslog messages written to the file. Now I can work on seggregating them based on host IP the messages are coming from. <br><br>Thanks all for you help with this.<br>

About the only thing I can think of off the top of my head. There might
be some sysctl option to disable UDP, but I dont know it if it does
exist.<br>

How come tcpdump output is seeing all the udp syslog-ng messages?<br>
<br>
[root@aspsyslog ~]# /etc/init.d/syslog-ng start<br>

if the problem is before it gets to syslog-ng or after. Shut syslog-ng
down and do 'nc -u -l 514' and see if it gets anything. That'll dump
out all traffic received. If it gets it, the problem is syslog-ng, if
it doesnt get it the traffic is getting blocked somehow.</font></font><br>
