It might work if your router have all of these settings available, I don't have other router to try myself. As you can see from the settings, it's bridging the IPTV signal from TM, you get an IP address in the range of 10.X.X.X when connected to the new SSID. The other feature needed is port binding to route all IPTV signal to a specific port, which is SSID2 in this case.
