I am looking at setting up some kind of visitor wireless access for our company however our internet connections all run through a external proxy.
After many wasted hours explaining to visitors how to enter the proxy settings before they can connect to the web I feel it is time to look at a solution which is a bit more simple from the end user point of view.
My initial idea was that I could just buy a WAP which allows me to select the proxy server but in reality this seems to be quite a rare or expensive option (I have had previous experience using a ZyAIR G-4100 for something similar but this was quite unreliable)
From a bit of research the most popular answer seems to be to setting up a transparent proxy using a Ubuntu box running Squid between the modem and the switch.
Does this sound like the most sensible idea or am I overcomplicating things?
Edit Forgot to mention that my other problem is that i am locked out of the router too so am unable to play about with creating separate subnets that bypass the proxy.
