use one tmg as a proxy for another

Hi Everyone

I have been asked to link a TMG in another country to a TMG in the UK to share the UK internet connection. This is for Web Access (ISA) usage.

The idea is the users in the EU country will use the TMG in that country in their native language and have tighter controls but no direct access to the internet, this EU TMG then forward requests to the UK TMG Array which has the single access to the Internet.

I figured it would be a case of adding the UK TMG details in to the EU TMG for access to the internet. Just not quite sure how to go about it.

Any ideas? Many thanks for any advice.
