Can anyone explain if there is a problem with double nating if set up correctly, I support a large primary school’s network in Sefton, and it has 3 Server and 150 PCs & Laptops. It is setup behind a Linux gateway\proxy box which acts as a gateway for the network, this box has two network cards and the second network card is attached directly to the local authority’s switch, where their responsibility ends. From my experience this is a normal setup for most school networks and I do support schools in other local authorities and there have been no issues with this type of setup. The local authority has put out it ICT support to a company called Arvato, whose technicians seem to go around the schools telling them that they should not have a proxy server on-site as it slows down the Internet and that they should be on the local authorities IP range, as double nating causes problems. The problem I have with this is that Sefton's network is like one large network, you can see any other machine on Sefton network and when it first launched there were lots of viruses spreading between sites if they were not protected by some firewall. I could understand it if they wanted to provide a managed service to the desktops, but they repeatedly insist that their responsibility ends at the switch. I understand the NAT adds legacy to a network, and a proxy server will slow down the first client to access a web page, but will speed up the subsequent request to the same page. But can anyone else see any good reasons not to have a proxy\gateway server at the point where your responsibility ends for your network, as from my perspective the benefits seem to outweigh the disadvantages. Thanks
