Hello,

# Log all incoming TCP packets
iptables -A INPUT -p tcp -j LOG --log-prefix "---[LOGGED (INPUT)]:--- "

# Log all incoming UDP packets
iptables -A INPUT -p udp -j LOG --log-prefix "---[LOGGED (INPUT)]:--- "

Note that these rules will log EVERY INCOMING PACKET and your syslog 
logs will get pretty big.
