I am unable to configure network devices through ISA via their web configuration pages. (Switches, Routers, H.323 Codecs, etc.) I can pull them up and log in to them but when I make any changes to their configuration pages and submit them they do not accept the changes. It works fine on a computer outside of ISA. I have ISA wide open for my user. I can configure these devices using a telnet session through ISA. Any suggestions would be greatly appreciated. The command line configurations can be quite complicated, where the web base config is much easier. Thanks
