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" Ian -------------- next part -------------- A non-text attachment was scrubbed...
