[FW1] Browsing problem with IE after enabling Client Authentication

["Cahill, Enda" <ECahill@FW1-NOSPAMawg.ie>]

Hi all,

Any suggestions appreciated.

We are running FW-1 4.0 Build(4066) on NT 4.0 Service Pack 5.  After
implementing Client Authentication via Radius on accessing the Internet
(Http and Https) all users using Internet Explorer 5.5 and 5.0 are
experiencing difficulties, i.e., some of the images on a page won't load
and/or receiving server not found messages.  On refreshing a page or
returning to a page these problems may or may not be resolved.  

Users with Netscape 4.6 are experiencing no difficulties whatsoever,
likewise users which are using IE but are not being authenticated.  If
authentication is needed it is specified by subnet.

The 2 relevant rules are...

Source				Destination 		Service
Action
___________________________________
Authenticated Networks		Any
Http/Https/proxy_http->http_OutBound		Client_Auth
___________________________________
UnAuthenticated Networks	Any
Http/Https/proxy_http->http_OutBound		Accept

The browsers are set-up with the firewall as the proxy address.

Thanks for your help,
Enda
