I'm running FreeBSD 5.4-RELEASE. When I load ipfw.ko I get: ipfw2 initialized, divert disabled, rule-based forwarding disabled, default to deny, logging disabled I want to use the forward action in the rule set, logging would be nice too. When I try to add a rule which uses the forward action, I get: Line 2: getsockopt(IP_FW_ADD): Invalid argument and line 2 looks similar to: add 1200 forward ##.##.##.1 src-ip ##.##.##.0/23 in recv dc1 At this point I'm guessing that "rule-based forwarding disabled" has something to do with it no liking my rule. I tried adding "options IPFIREWALL_FORWARD" to the kernel config and rebuilt the kernel. But I still get the same message as above when loading ipfw (kernel module). I've perused all the relevant sections of the handbook that I could find without finding any more clues. What does it take to change the default feature set of the ipfw kernel module? Or do I have to compile it into the kernel to alter this? Thanks for your suggestions, Jon
