I need some advise on a very unusual problem.
We have a cisco wireless lan controller which has a dsl connection out to the internet.
The way it works is that a client types in the url www.bbc.co.uk. The wireless controller will validate the authencity of the web address before presenting the client with a landing page for authentication which is 126.96.36.199.
If the web site is not valid, a page cannot be displayed error is returned. If it is valid , client authenticates on the 188.8.131.52 page and is allowed access.
This is the way it has always worked. But there is a new problem now where the wireless lan controller is not presenting us with the landing page , we are having to type it in the url manually which is an inconvinience for most end users.
Funny enough if you input the management address of the dsl router, you are immediately presented with the landing page.
Any ideas, guys and girls.
