Probably= TCP RACK is not supposed to support TCP MD5 and this bug has to be closed, but = let people from the project decide and give some feedback here. I have done more tests with the most recent stable{12,13} and it looks like that with net.inet.tcp.functions_default=3Dfreebsd TCP MD5 signatures are supported fine. I have tried to revert this setting to default prior to reporting this as a bug but it not always worked. I am sorry for the noise on Bugzilla and freebsd-net@ mailing list, but in initial tests disabling RACK wasn't sufficient to get TCP MD5 working (prob= ably due to accidentally flushing IPsec rules in the meantime), so I took some ad-hoc steps to repair it quickly, disabling some devices, reverting sysclt= s to default values etc. --=20 You are receiving this mail because: You are the assignee for the bug.=
