Can some kind soul briefly explain to me what 'Loopback' is, in the context of a firewall such as ZA?
In Program Control, I have the two Access categories for Internet Explorer (iexplorer.exe) allowed, but for the two Server categories I have their entries questioned and blocked. So, I think I'm configuring Internet Explorer properly. However, when I look in Alerts & Logs, I see that, on occasions, iexplorer.exe makes what appears to be an arbitrary attempt on a port of 127.0.0.1. It's referred to by ZA as 'Loopback'. Is this some sort of internal function confined to within the PC, or is it possibly a connection made to the router? My router is, as you'd imagine, in the Trusted zone. Obviously, the attempt is permitted.
