Hello everyone,

I bought a MR-100 a few weeks ago and I'm using this device since then. To add some security features, I put a Mikrotik behind the MR-100 and the Mikrotik is providing internet to my home network (using the DMZ option, I forwartded all the incomming trafic to the mikrotik). I want to setup a 6to4 tunnel on the Mikrotik but it is not working. It seems that the MR-100 filters the 6to4 tunnel packets. the tunnel gets established, but I cannot see the other side. I checked all the settings and even disabled the firewall on MR-100, but nothing changed. 

Note that to check my provider it they support this kind of tunnel, I replaced MR-100 with another device (not from TP-Link) and the 6to4 tunnel works fine. Would you please help me resolve this problem?

Best
