Hello,

I am trying to set up a 6rd IPv6 Tunnel to get ipv6 to work between my LAN and my ISP.

Unfortunately while configuring the required settings, I am encountering this issue where as I try to save the configuration, when the page refreshes the "Enable" checkbox gets unticked, although I had it ticked before.

This happens without any error notifications of any kind (and I experienced some error notifications during configuration, so there is some error checking), it just unticks.

I'd like to make ipv6 work but I am stuck here since it silently fails.

Any help would be apreciated, thanks.
