rsub doesn't bind IPv6

[brianbienvenu]

When connecting to IPv6 remote hosts, I get an error using rmate:
connect_to 127.0.0.1: unknown host (nodename nor servname provided, or not known)

If I change RemoteForward 127.0.0.1:52698 127.0.0.1:52698 to RemoteForward 127.0.0.1:52698 localhost:52698, I get this:
connect_to localhost port 52698: failed.

This is because rsub isn't binding tcp6 port 52698 on my local computer:

$ netstat -anl | grep 698
tcp4       0      0  127.0.0.1.52698        *.*                    LISTEN

A terrible workaround:
socat TCP6-LISTEN:52698,fork,bind=[::1] TCP4:127.0.0.1:52698

Is there a nice way to add IPv6 support to rsub?

On Windows client my workaround is to use port proxy:

 netsh interface portproxy add v6tov4 listenaddress=::1 listenport=52698 connectaddress=127.0.0.1 connectport=52698
