I'm not clear what you want to do. Do you want to do a DNS lookup on the 
rejected packet source IP and log the source name rather than the IP? If 
so I don't know of any way to change the content of the log entries 
generated by netfilter. You could always write a script to parse the 
logs, resolve the IP, and re-log it with the name.

You're receiving packets from the outside world destined for your 
private lan IP address? Could you post the relevant rules from your 
chain and a few log entries that show this?
