Recently my router stopped giving raw logs of the websites being accessed and switched to logs like this:
[LAN access from remote] from
or UPNP SET EVENT: etc.. Netgear wndr3400.. a common issue going on, if it's even an issue. I can't seem to understand what people mean by UPNP is enabled and this is what's causing it.
So basically my questions are:
Why is UPNP on? If there is a reason, it wasn't turned on manually.
What is UPNP? (Other than its acronym)
Will it do any harm if I switch it off? (however I do that)
