[Bug 730620] [NEW] After disabling ipv6 port forwarding does not work anymore

[inode77]

Public bug reported:

After having disabled ipv6 (sysctl) local port forwarding does not work
anymore.

debug1: Local connections to LOCALHOST:8080 forwarded to remote address 127.0.0.1:80
debug1: Local forwarding listening on 127.0.0.1 port 8080.
debug1: channel 0: new [port listener]
debug1: Local forwarding listening on ::1 port 8080.
bind: Cannot assign requested address

This is not a behaviour I expected and it went away when I reenabled ipv6.
Please advise how to disable ipv6 but keep openssh functionality.
