I've recently been asked by our networking department to see if it's possible to have the ZENWorks Endpoint Security client not pass traffic through the proxy server.

I haven't been able to find a lot of information on the subject as to whether or not it's possible to configure the client so that it doesn't pass through the proxy server (other than a post that suggested setting the LAN for bypassing the proxy for local addresses), but I would assume, based on the fact that traffic does seem to pass through port 80, that it would require access through the proxy as a result - especially if the client is outside our network trying to update itself from inside.

Is that a correct assumption? Or am I misinformed?

Any suggestions would be really helpful - thanks.
