Hello community,

I am trying to set a '6in4 tunnel' on my FritzBox router.
I am now trying to figure out, which bits of information need to go in which fields.
In the setup dialog I am being asked for the followings bits.

IPv4 address of the tunnel endpoint
IPv6 address of the tunnel endpoint
Local IPv6 address
IPv6 prefix

And from the 'IPv6 Tunnel Endpoints' page I have the following bits.

IPv6 Tunnel Endpoints
Server IPv4 Address: xxx.xxx.xxx.xxx
Server IPv6 Address:
Client IPv4 Address: xxx.xxx.xxx.xxx
Client IPv6 Address:

I already managed to figure out the bits for the IPv4 fields.
However I don't know where to find bits for the following fields for local IPv6 address and IPv6 Prefix.

Thx for the help, user3636


You match up the data you have from HE to the fields below.

Tunnel end points are given to you by HE
local ipv6 address is the client /64 given to you by HE
prefix is /64 (unless you signed up for a /48)
