Hello,
I think this is a bug with ROS6b2
I have successfully made connections using both 6to4 and also he.net tunnelbroker (at the moment I prefer tunnelbroker although native from my ISP would be preferred still!)
When I first created the firewall rules, each rule I added seemed to affect the counters for the firewall

If I reset the counters then these counters act “normally” until I edit a rule and then the counters are affected as per the picture.
Regards
Ian
