Step by step, this all i done:
1. Rebooted modem, wifi repeater and stb.
2. I performed an iptv reset from the web page
3. I use a dummy MAC number for each of the routes, apply, and then i changed again to the real route.
4. I switched the route in each stb, alternating each one, an then "apply"
5. Several times a clear the stb emu app and I rewrite the profile info.
6. Combinations of all above.
Results: "STB Blocked, STB Blocked" etc.
So, there's any other solution?
