I thought  iptables -L |grep udp   will show me, but instead it 
shows:
Use the holy -n option.
OK, Jan, I'll bite. WTF is the "holy -n" option?
`man iptables`

   -n, --numeric
      Numeric  output.   IP addresses and port numbers will be printed
      in numeric format.  By default, the program will try to display
      them  as host names, network names, or services (whenever applicable).

In other words, it will print 3128 instead of ndl-aas.
