Hi All Just built a new kernel with options IPFIREWALL options IPDIVERT and all went in ok. However, when I user the ipfw command to add a rule (or when rc.firewall does) I get the following error message:- ipfw: getsocketopt(IP_FW_ADD): Invalid argument Can anyone point out the obvious mistake I must be making? (4.2-STABLE install from the CDRom) Cheers Ak To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-net" in the body of the message
