For what it's worth, I'd like highlight a key point I think is missing, = in the ipfw section of the Handbook. This has been discussed earlier = with help from this mailing list community. I am just formalising the = documentation. The firewall that comes with the default kernel (at least on the 5.4 = release) comes with forwarding disabled. As a result, if you try to do a = ipfw fwd (or ipfw forward), you will get a getsockopt error. The Handbook (at this time of writing) did not mention the inclusion of: options IPFIREWALL_FORWARD Recompiling the kernel with this thrown in will activate forwarding by = default. I do not know if there is a sysctl parameter which can avoid = the kernel recompile. If there is one, kindly contribute to the = knowledge base (aka mailing list). Hopefully this post will save the next FreeBSDer precious time.
