Re: 'Internet Explorer cannot display the webpage' issue
Yup thats spot on, for generation 1 appliances (Protego ones) 4.3.5 is the latest version. For gen-2 its 5.3.5 I think. Let me know how the GUI thing turns out.
Btw, if you have important data on your box you have to go through the upgrade process. You cannot directly install 4.3.5. You have to go through many updates in the middle to get this done. If the data/configs are not important and can easily be done again, you can just re-image your box from a boot-cd and that will take you directly to the latest version.
