This would solve the issue for my use case and should not break anything (a few UNKNOWNs will become TCP6 then). I can rework the patch, if technical changes look good to you. There's a ton of memcpy in there to not destroy the data structures needed for the actual communication: make_proxy_line() now always operates on a copy of `struct connection remote`. I could not find a better solution and already thought hard about the current version. Best regards Tim Düsterhus
