Blocking UDP traffic

Post by gberger » Sat Jul 14, 2007 10:00 pm

Question for a tecchie.

I'm running a single iMac G4, OS 10.4.6, via dial-up (shortly to convert to cable broadband).

My OS X firewall is set to deny UDP inbound traffic, as I don't game or download streaming video; however, LS default allows outbound UDP traffic on certain ports to certain addresses.

Should I change the permission for outbound UDP traffic from accept to deny? Does it matter?

TIA, George (The Old Fud)

You probably have found the answer to this, but you should most certainly allow certain types of outbound UDP traffic, most notably:

* DHCP (also called "bootp")
