IPv6 to IPv4 converting - tunnel between to ubuntu servers

I live in a country that recently launched a heavy censorship protocol on Internet. most of the IPv4s are restricted or completely banned.

I have two servers , one in my country and another one in Germany that has access to free internet.

I need to figure something like this

using this command to make the tunnel :

ssh -v -N -f -L [local_ipv6_address]:[local_port]:[remote_ipv6_address]:[remote_port] [user]@[server]

but the tunnel needs to be translated atleast at the client side (my ISP doesnt support IPv6) I need a help to do that.

You can tunnel IPv6 over IPv4-ssh connection. There's no translation needed - the client to server connection can run over IPv4, and transport IPv6 packets.

OpenSSH can create a Socks Proxy (-D <port-number> cmd line argument) that can be used to tunnel most traffic.

e.g. you can enable a socks proxy for Chrome with the following cmd line argument --proxy-server="socks5://myproxy:8080" where myproxy would be your local server and 8080 would be the port number passed to the -D argument.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
