Remote access to UK content

I frequently travel outside of UK and struggle to reliably access UK entertainment content like the BBC even with a good VPN. Years ago I saw a solution based on a SBC with an ethernet and WIFI interface on a UK home LAN with a UK ISP. Non UK requests for content were received on one interface and passed to the other interface which was not blocked, replies were handled in the reverse direction. I cannot locate the original document now but here are the few things I remember; remote access was configured by a port forwarding on the router; routing and NAT tables were configured to handle the requests and replies and masquerade option was used. Sorry my information is very limited.
Can anyone point me in the right direction to realise such a solution or related informations for me to develop my own solution.

You just need a device on your home network that runs a VPN server. That could be a standalone device like a Raspberry Pi, or it could be your internet router as many of them have that ability.

Another alternative would be to get yourself a cheap VPS from someone like OVH (yes, they have UK servers with UK IPs) and set up a simple vpn on that. Plus point on that is 24hr availability where we know home routers can crash.

Amazon Firestick 4K Max, when bought in UK, comes with all those UK programs and has apps for many others.
Install your VPN also on that Firestick and watch it anywhere on a TV with HDMI-port.
PS: don't forget your remote and don't leave it behind in your (hotel)room.
