Route subnets through a remote server/proxy

[LucaTNT]

Hi guys,
A few sites I want to use are blocked from my ISP, I can get their IP addresses using third-party DNS servers but I cannot connect to them.

I have a Linux server abroad which I'd like to use as a relay to access these sites, and I would like to have pfSense handle the routing, so that I don't have to fiddle with the configuration of each client on my network.

I am an absolute novice at this stuff, what can I do to achieve my goal?

Thanks to every one, any help is really appreciated.

Luca
