IPv4 to IPv6 proxy

Sun May 29, 2011 12:46 am

Has anyone tried to make a proxy for IPv4 clients to access IPv6 content? I am looking for a way to do a transparent proxy that will allow my v4 users to access v6 sites. Any suggestions?

Thanks

It would be more useful the inverse: to allow IPv6 only users to access IPv4 content.

Yes ... I'm interested in this too. Everyone is talking about transitioning to IPV6. How is a gradual transitioning possible? When my server has only IPV6 address, how can IPV4 clients reach it ... and suppose my ISP switched my residential addressing to IPV6, how will I be able to reach IPV4?

It's called NAT-PT or NAT64. RouterOS does not support either currently, some other router vendors do.

It's more of a last resort, though. A gentle transition mechanism is dual stack where as things move towards native IPv6 everywhere the IPv4 portion of the stack becomes increasingly NATed (via well established NAT44).
Specific answers require specific questions. When in doubt, post the output of "/ip address print detail", "/ip route print detail", "/interface print detail", "/ip firewall export", and an accurate network diagram.

NAT64 is for pure IPv6 clients to access IPv4 content, Depending on the vendor you can do somewhat limited and buggy IPv4 access to IPv6 but it's not in the RFC.

Currently there is no stable or RFC based way for IPv4 clients to access IPv6 content and I doubt there ever will be. The widely accepted transition method outside of mobile markets where NAT64 is aimed is to dual-stack with public v4/6 and then move to CGN(NAT44) and public IPv6

You need to add a 6to4 tunnel with some tunnel broker and route IPv6 traffic to them. There's some guide in Wiki and here is some tunnel broker: http://tunnelbroker.net/

I am already setup with a tunnel broker. I am just looking for a way to have v4 access v6 sites, unfortunately most routers (Linksys, Netgear, D-Link) has little if any support for v6.

Also has RouterOS have support to give out IPv6 addresses via PPPoE services. This will be nice to have at least one step done for a finel solution (once router manufactures support IPv6).

It's against IPv6 transition plan (you know.. forget ipv4 and move to ipv6) so I don't think it will ever get to life.

what if you setup your browser to use proxy with address = your router, connected to ipv6 network?
