Subject: ipfw should pass all lo0 traffic, not just 127.0.0.1

ipfirewall

>Description:

My firewall config logs these:

Oct  5 19:05:24 dial /kernel: ipfw: 40300 Deny UDP 204.147.226.8:1018 204.147.226.8:111 via lo0

The problem is the routing table:

myname             0:60:8:2a:a6:b3    UHLW        1       14       lo0

>How-To-Repeat:

>Fix:
	
The solution is to change the line in /etc/rc.firewall

/sbin/ipfw add 1000 pass all from 127.0.0.1 to 127.0.0.1

to

/sbin/ipfw add 1000 pass all from any to any via lo0

Perhaps a better fix is to not send non 127 traffic to lo0.
