Hi Scott, You've entirely missed my point. Yes, if I connect directly to a host, I can use '-4' to force IPv4. When connecting through a proxy, I can't easily control which address family to use, nor the TCP connect timeout. Sure, if I use netcat to proxy, I could supply a '-4' to it to force connecting over IPv4. But making that permanent is also a pain because I want to connect to IPv6-only hosts too. But none of these individual fixes are relevant. I would like a finely-tuned ssh config, with a proxy setup, whereby connecting to remote hosts doesn't take so long because of the default TCP timeout. My use case is connecting to several hosts with ansible using ssh as the transport. I can't adjust my ssh config for each host. If IPv6 is not working for a host at the time I'm connecting, I'd like the proxy to quickly fall back to IPv4. Later, if that host's IPv6 is working again, I'd like to be able to use it without hacks.
