We use one of these at work on a broadband connection that is setup just to service guest web access from our site. I would like to be able to manage it a little more convienently. Right now I have to connect to the network it is on in order to bring up the admin web page. Would be nice if I could some how lock down the WAN port after enabling it for remote management. I have tried using ACL and the mac addr of the WAN port, but that doesnt seem to work, or maybe I am just setting up the rule incorrectly..not sure. I'm not really that familiar with this device. If someone could flat out say you can't do it, I'll stop banging my head against the wall and either give up or get a small ASA 5505 or something for this.
Thanks
