wingate www proxy - bypassing authentication for a/v updates

[noelwelpton]

I have a number of pc's behing a wingate, using www proxy, all users required to authenticate manually at connect time. Works well in controlling inet access and use.
I need to find a way of allowing pc's to bypass authentication overnight, for example, to permit anti-virus updates. There are specific url's for these.
I think it can be done by the policy rights in the www-proxy settings. Am I on the right track, before I spend too much time on it, or is there a better way?
Thanks in advance (hopefully).

You could set up a second WWW Proxy service, using a different port (eg 8080). Create a group to hold all the users who have to update AV, add this group to the policies of the service. In the policy properties of the group, allow either assumed usage or unknown user, then create an advanced request rule to only allow access to the AV update URLs. you
could additionally set time restrictions for these connections.

We use something similar to the above for our central Windows SUS server.

Thanks. I thought of that as an approach. The problem here is that Norton, for example, uses the inet settings from Internet Explorer to configure its internet access. Thus it will go to the standard user proxy setting.
Unless you know of a way of altering NAV network settings. I shall peek into registry, perhaps?

Norton, for example, uses the inet settings from Internet Explorer to configure its internet access.

Not true: NAV uses settings from liveupdate.
Theese settings are defaulted to IE's settings but can be changed in the liveupdate configuration.

Hope this helps :)
