i have an issue with one of our customer , they have a wireless network were users are using laptops and smart phones as well to access the network. to get internet access users have to enable proxy.
using laptops they will connect through wifi and they can access all internal network resources like emails and other internal applications, but they need to enable proxy to get access to internet. this case users who enabled proxy will also do exclude proxy for internal ip range.
but unfortunately smart phones normally doesnot have an option to exclude proxy for some ip ranges.... so smart phone users while they enable proxy they are able to access internet but internal resources will not be able to use as all the traffice from smart phone will be forwarded to proxy and proxy can forward its traffic only to its gateway.
how narmaly you guys fix this probelm ..i belive this probelm faced many of us before.
