IPv4 in IPv6 tunnel

[eriza]

Hello,

I've been playing with the 2.6.28 and 2.6.29 kernels, and discovered the "ipip6" tunnel mode in the "ip" man page. If I guess correctly, this should be the IPv4-in-IPv6 tunnel, is that correct? Can anyone confirm this?

However I didn't manage to create any tunnel, e.g. using the command:

# ip tunnel add mytun mode ipip6

as root, produces "Cannot guess tunnel mode" error message.

Is it possible at all to create this kind of tunnel? If yes, how?

Thanks,

Hi eriza
I saw an article which may help you. URL Displaying existing tunnels
There are several pages you can move between. Seems to be extensive and hopefully it helps. Cheers...

Hi Robert,

thanks for the article. I still have no luck, though. The article says I should've used "ip4ip6" instead of "ipip6". Which I tried; still getting the same error message.

It also mentions that the IPv4-in-IPv6 tunnel has been supported since kernel version 2.6.22. I'm currently using 2.6.29, so it should've been supported. Just can't figure out how.

Rgds,
