https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=231143 Bug ID: 231143 Summary: Ipfw fwd with route(8) RTF_BLACKHOLE and fast forwarding on FreeBSD 11 Product: Base System Version: 11.2-RELEASE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: misc Assignee: bugs@FreeBSD.org Reporter: run00er@gmail.com A situation has arisen in which ipfw fwd stops working when RTF_BLACKHOLE or RTF_REJECT, ROUTE (8), is enabled on Freebsd 11 release. FreeBSD 11.2-RELEASE-p1 route add default 127.0.0.1 -blackhole –iface ipfw show 00100 30 4056 fwd 10.0.0.5 ip from table(1) to not 10.0.0.0/8 in via em0 The packet counter changes, but forwarding does not work. On FreeBSD 10 everything works fine. I suppose this is due to changes to forwarding -> fast forwarding by default in FreeBSD 11 and man ROUTE (8), “BUGS - unless IP fast forwarding is enabled, in which case the meaning of the flag will always be honored.” -- You are receiving this mail because: You are the assignee for the bug.home | help
