Hi,

We encounter a problem with web AUthentication fallback in a catalyst 3750.

We configured 802.1x on the 3750. This works great but the pb is with the fallback Webauth. When the client has no proxy configured there is no pb; I mean the client is prompted with the authentication webpage. But if the client has a proxy he doesn't. The client can browse internet throught the proxy but the switch port remain in the INIT state of ip admission and is never prompted:

Authentication Proxy Cache

Total Sessions: 1 Init Sessions: 1

Client IP 10.166.194.54 Port 0, timeout 1, state INIT

So he can't do anything else that browsing internet...

Any idea about how to access the authentication webpage if there is a proxy configured in the browser ?

Thanks for your answer
