I have a vpn 3005 concentrator that I cannot log into the web administration page for. When I access the concentrator I get a HTTP 403 Forbidden error. From IE, the error detail is "This error (HTTP 403 Forbidden) means that Internet Explorer was able to connect to the website, but it does not have permission to view the webpage." I've tried multiple machines, and Firefox as well, but all give the same error. I have no trouble with administration via telnet, but would like to get the web interface working again. I even tried updating the concentrator to 4.7.2.P (from 4.7.2.O) but that didn't solve the issue either. I also noticed an error in the event log that shows the request and a HTTP 404 Not Found (/) error. Any ideas?
On your interfaces, e.g., "Configuration | Interfaces | Ethernet 1", on the WebVPN tab do you have the box checked for "Allow Management HTTPS sessions"?
