ipv4 to ipv6 using SSF - quick / simple

allendiggity

I know this can be done using wireguard, but have had trouble getting ipv6 routing working on my OpenVZ 6 VPS, and am waiting to be migrated to OpenVZ 7, when I will use @Nyr 's excellent wireguard installer. Thank you @Nyr .

In the meantime, this works, at least for me: https://securesocketfunneling.github.io/ssf/#how-to-browse-privately

ipv6 test using chromium-browser on linux connected via local SSF socks5 proxy to SSF server on VPS:

Addendum: I can also use this to ssh into my ipv6 only free server at Euserv.

My ~/.ssh/config

# euserv #
Host euserv
     HostName server_ipv6_address
     User root
     Port 22
     ProxyCommand=nc -X 5 -x localhost:9000 %h %p

Local ssf socks5 proxy is running on localhost:9000.

Does this work if you have no ipv6 connection at all?

The SSH thing.

My current ISP does not provide ipv6, and my current ancient router cannot route ipv6, so I use this method at the moment to access the ipv6 internet via my MrVM VPS that has both ipv4 and ipv6 addresses. I did not need to do any special configuration on the VPS, other than running the SSF server on it.

So yes, it works for SSH.

I guess the same could be achieved just connecting to the server via VPN, like Wireguard.

Yep, as stated in my OP - not working for me at the moment, hence the workaround.

@allendiggity Thanks for posting this. It's interesting! I didn't know about KIT or SCC.

The URL for the IPv6 connectivity test page, a screenshot of which was posted by OP @allendiggity, seems to be [http://wieistmeineip.scc.kit.edu/]{http://wieistmeineip.scc.kit.edu/).

This solution of using your own VPS's SSF seems maybe more private than, for example, Hurricane Electric Free IPv6 Tunnel Broker.

I think that's a mirror URL - you can just use https://test-ipv6.com/
