Proxy server for changing geolocation - recommendations wanted

[Chris Green]

I want to set up a simple proxy server so that I can use my UK library
services and my doctor's web site when I'm abroad (specifically when
I'm in France).  In addition it would be handy to use Google Shopping
(for example) when I'm in France but want to search UK suppliers.

So, while squid is the 'default' proxy server for linux/ubuntu it does
seem to be heavily oriented towards use as a LAN proxy for handling
multiple LAN clients' access to the internet.  It looks to me as if it
would be rather clumsy to use for my application.

Are there any other proxy servers that offer a simple way to allow
access from remote locations (which don't have a fixed IP as I will be
using my laptop via all sorts of different means) and will then
forward my requests as if they were from the server where the proxy is
running.  I can't see any (simple) way to get squid to do this, it
*can* do it but doesn't seem the ideal tool.
