700wl Proxy redirect problem

Jason Baird — Tue, 28 Feb 2006 08:46:34 GMT

I follow the directions for setting up http proxy redirect on the 720 but the wireless tablet does not receive the proxy info. I am at firmware 4.1.93. Any help would be appreciated.

Actually it all works fine if I have the proxy set in IE on each client. But it doesn't work without it. Any ideas?

It doesn't sound like it's set quite right. Are you using an external proxy server or the built in proxy of the 720/740?

As you know, the proxy redirect will intercept traffic destined to a particular port and automatically proxy it without any changes to the client.

These things can obviously be difficult to configure, I'd recommend you contact your procurve rep about it to see if they can help, otherwise support may be able to assist in checking your config.

The proxy server is an internal server on our 10. network.

It seems like the 720/740 just doesn't pass the proxy info into IE? What am I missing?

That's right, it does not pass any proxy settings to the client.

It acts as a transparent proxy. It's main purpose is to give web access for clients that are not configured correctly. It's designed for guests that have come in and don't have the proxy settings configured correctly for your network.

Regular users should set the proxy in their web-browser settings, either manually or automatically using PAC or a group policy.

If all users were to rely on the proxy redirect, the 720wl's performance would eventually suffer as it has to intercept each and every packet on those monitored ports (e.g. 80:8080:3128)

So do I setup proxy in the network settings for the Access Controller AND enable proxy on each access policy (ie unauthenicated,guest access)?

I appreciate all your help so far. Thank you.

And monitor ports 80:8080:3128?

That sounds about right. Read the Access Policies chapter of the Management and Configuration guide. There is a HTTP proxy example at the end of the chapter.

Also I'd recommend you update to the latest software 4.4.0.50, it has a few enhancements to the HTTP proxy feature.

The funny thing is when I read that chapter it makes perfect sense. But when I compare the Automatic HTTP Proxy screen in the manual has fields for Proxy Server and Proxy Port. Mine however only has Automatic (enabled or disabled) and Monitored ports. The proxy section is missing completely. Is this a problem with 4.1.93?
