Example: I try to create a rule to accept packets like this captured in debug mode: Dec 14 23:08:44 devilbox kernel: ipfw: 400 Accept ICMP:3.4 192.168.1.5 192.168.1.11 in via wlan1 Error when trying to create rule: # ipfw 500 add allow icmp from 192.168.1.5 to me icmptypes 3.4 ipfw: invalid ICMP type Exit 65 RFC792: ICMP type 3 (destination unreachable) ICMP type 3, code 4 (fragmentation needed and DF set) * This problem also occur in all ICMP types and codes. >How-To-Repeat: ipfw 500 add allow icmp from 192.168.1.5 to me icmptypes 3.4 >Fix: Create methods that make possible IPFIREWALL and ipfw interface accept specify ICMP codes. >Release-Note: >Audit-Trail: >Unformatted: _______________________________________________ freebsd-bugs@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "freebsd-bugs-unsubscr...@freebsd.org"
