Well if you want to use the Synology it is very easy to connect to a VPN provider as long as they use password authentication. Just use the VPN client app.
If using torrents you would probably want a VPN service that will allow you to forward ports. (Configurable through a website rather than a client app on a PC)

Airvpn use client/server/key certificates which requires a fair bit more work to use on a Synology box. Link.

If it were me however, and given your exchange with Bob, I would be looking to move to a different ISP. Rate limiting is so last year

Can't offer any other solutions to avoid traffic shaping if they are using clever DPI kit. A virtual private server/seedbox maybe but then I think that's moving into the realms of overkill just to bypass traffic management!

You could try a VPN for around a fiver if you just want to see how you would get on with it.

Thanks very much for all your help folks. I've decided that I'll just change isp and stop a whole lot of hassle. .........

Very wise .

Ian I do realise the things that I mentioned don't need vpn to operate but my isp in their great wisdom have decided to cap my connection when I'm downloading torrents. So this is why I'm looking a vpn.........

Aha, that is cool as that finally gives me a reason for someone doing it barring the obvious. Be interesting to know what the ISP thinks about people using VPN to get around their blocks though - especially if it is in their Ts&Cs. But, that is possibly the best reason for VPN I have seen to date.

If it is just for torrents, I would look at a seedbox instead. The torrents run on their server, then when done you download the file through your browser, the same as any normal download.
