Over the years I've used the following scenario for connections through Wingate: assumed users by ip address and computer name; connection via proxy, authentication required (java login) for certain users as defined in www policy, and trapping of port 80 requests coming through Extended Networking. I like to keep Extended Networking enabled to take care of TCP/UDP requests for NTP, windows update, etc. In Extended Networking policy, I have checked that certain users must be authenticated, however, I can't see much difference with that requirement since requests seem to go through regardless.
The above setup works well internally in my building. The problem that I'm seeing recently, is that outside the building on the campus, people are successfully connecting to the network on their iPhones, etc. and getting out via Extended Networking. Of course http requests are blocked by the www authentication requirement in WWW policy.
Can you suggest any setup change, particularly to extended networking? Of course the better solution would be for me to secure my APs. However, to do that I will need to purchase some new hardware because of the age of my current units.
Thanks, James
