I also believe that to be the case, although I would be only to happy to be corrected!
I am not too worried about the PCs, because like you say you can force the proxy in a couple of different ways. But I am concerned about mobile devices, especially guest ones, as they won't be part of our domain and we won't be able to force GPO's etc..., and the whole web proxy implementation is more for that kind of device on our network.
I am really struggling to believe that this router is unable to forward to a proxy, but I am stuck for ideas.
Thank you for your reply.
