   Thank you for replying to me.   
      
   My team and I have tackling this issue in our short-term plans. I will then   
   start a new thread, to keep discussion clear and with more technicalities.   
      
   But in a nutshell - we are sending immense amount of SNMP queries - which   
   equate to UDP packets and keep hitting EPERM if the iptables is up. We use   
   Java libraries for handling SNMP querying - snmp4j. I don't quite remember,   
   but running our app as a    
   restricted user or as a root does not make any difference.   
      
   I hope that using Google Groups as a gateway to USENET is OK. I am not really   
   sure what are proper ways to use USENET.    
      
   Thanks,   
   Rade
