Hi all, I was wondering if you can point me to a resource for HPs whitelist of its domains it uses for updates. I am running a Sophos firewall and want to update the BIOS using the UEFI interface in the BIOS. However it is getting blocked. I don't want to add an any-any rule as it defeats the point.
Any help would be appricated.

@Luke831 -- do you have another computer (or access to one in a Public Library, or a friend with a computer) that you can use to download the update, and copy the update to your USB memory-stick, and then connect that memory-stick to your computer, to execute the update?
P.S. note that if your computer is connected to a router that has both WiFi and multiple Ethernet sockets, that device is already working as a "firewall", to block all "unsolicited" incoming traffic to every computer on your local network. So, any software firewall won't see any of that "unsolicited" traffic. This leaves the router with a "black-list" of IP-addresses that it prevent you from accessing anything running on those IP-addresses.

Hi, thanks for the info, this could be done, however I was looking at a more specific solution as having the domains for HP updates. Updating the BIOS from the UEFI BIOS interface (White screen with mouse controls) not the old blue BIOS screen which I believe does not have the function of updating the BIOS from there.

@Luke831 -- I do not see any advantage to "white-listing" a limited set of websites, and "blocking" every other non-listed site. That's a lot of work by you, as your needs change.
> not the old blue BIOS screen which I believe does not have the function of updating the BIOS from there.
I disagree with your belief. Before UEFI interfaces superseded the "old-school" BIOS interface, every BIOS that I have used had an option to update the BIOS.
