Hi @YESSS_Connect
Thanks for posting in our business forum.
You need to use a VPN. I'd recommend you use L2TP VPN which you can set up the Policy Routing to route TV or other types of devices to the L2TP VPN tunnel. Then enabling you to access the TV service.
However, I would highly recommend you set up the VPN on the client/device instead of the ER7212PC.
Mainly because it would be more convenient to control the access and this will allow more VPN types if it is based on your client system. Omada system now only allows the L2TP VPN to use the Policy Routing which would be a feature involved in your setup.
Moreover, you need an IP address located outside the UK if there is geo-blocking. I mean a VPN server, a provider that gives you the IP bypassing the geo block.
