Adding a router to the firewall exceptions?

This message keeps repeating endlessly in var/log/ipfw.log:


65534 Deny UDP 0.0.0.0:68 255.255.255.255:67 in via en0

Jun 21 09:46:47 ipfw[311]: 65534 Deny P:88 2xx.10.46.1 224.0.0.10 in via en0


The xx IP in line 2 is my router. How can I stop this error?


Thanks for your time - it's much appreciated.

First off, it's not an error. At least not technically.


The traffic it's reporting is merely standard BOOTP/DHCP traffic. I'm guessing your router is also your network's DHCP server and it's sending out normal broadcast traffic as part of its DHCP-related duties.


If you want to stop the logging, either set a rule in the firewall with a no-log option, or turn off the firewall altogether - if you're on a private LAN protected by a hardware firewall there it little to gain in running the software firewall on your server.

Yes I'd like to add a no logging rule. Any sites you'd recommend for learning how to do this? Can I do this via the GUI? I understand the services, but couldn't easily see a way to disable logging on a per address basis.This server experienced a DOS attack a few years back and I'm paranoid about it happening again. Thanks for the reply.
