Cannot Setup 6RD Tunnel
I have the problem that I can't get an IPv6 address through the 6RD tunnel and I have no idea what I did wrong. According to my ISP I get an IPv6 assigned to the tunnel from the server. On my other router it also works without problems. However, it does not work on the firewall for some unknown reason.
Here are 3 screenshots of the 6RD tunnel on the firewall and of the information from my ISP and of the Config on my Router:
