IPv6 connections over SSH SOCKS server tunnel to a possible DNS server

• Provide a SOCKS server by an ssh-tunnel to your remote DNS server:
  ssh <DNS-server> -N -D8080
• Configure firefox for the usage of the SOCKS server:
  Edit -> Preferences -> Advanced -> Network -> Settings
  Manual Proxy Configuration:
    SOCKS Host: localhost:8080
    Let HTTP, SSL, FTP Proxy empty!
  Visit: about:config
  Set network.proxy.socks_remote_dns = true
  Restart firefox
• Visit kame.net - the turtle should dance if IPv6 is working. 

You can use your new SOCKS server port (8080) not only by a web browser (as it's shown for firefox) but also for another applications.

• For using the new SOCKS port by your ssh client, e.g. to reach your-ssh-server. net with only an IPv6 address, just type:
  ssh -o ProxyCommand='nc -x localhost:8080 %h %p' name@your-ssh-server.net
