If you're using IPTABLES on your CentOS box, then you can "watch" the 
traffic hit your rules using "watch -d iptables -nvL".  The -d will 
highlight changes (so you can spot them) and you should see the number 
of packets change as each packet is processed by your rules.

If you have a specific chain name that deals with your port, then add 
that after the -nvL in the command - e.g. "watch -d iptables -nvL myChain"
