thanks for replying.
but what i see it works without adding the porotocol 41, so do i still add it (i added it anyw way yesterday), but it was working anyway. is it pre-built already?
Ciao!
How are you?
I use HE.net tunnel, but my question is, how come it was working without adding it into the firewall, although I added, but is it built in now or what. Do you know?
I believe protocol 59 was added into the wiki recent because someone noticed something and someone else thought it was required. My 6in4 has never required 59 to function. Protocol 41 is required if you are initiating v6 connection from the outside. If that's not the case for you, I'm sure you can remove it.
My own protocol 41 is "strict", allow from only one of HE.net tunnel IP, not globally.
I never needed it with my old SixXS tunnel, and also he.net tunnel operated ok without that. (But I have now a native ipv6, so I haven't looked into that recently.)
But it is quite possible that he.net uses that protocol for some kind of "tunnel alive" monitoring, or so.
