Router log entry puzzle
I'm just a single user, don't host. Have a Netgear router fed by ethernet adsl modem. I onlly look at its firewall log every other weekend. I noticed a 'drop' line I'm sure didn't appear before - I don't copy the logs. Like this:
(timestamp) TCP packet, source: 127.0.0.0,80 [http] wan, - destination (my dhcp addr here) lan - inbound rule match - drop
Specifically the source entry, whereas all the other 'wan' entries for any packet type are obviously snooping external ipv4 octets, and a few I recognise as in my ISP subnet. That entry appears about every 6th entry but it varies.
I know the browser uses port 80 but I'm lost as to why that 'localhost' 127..0.0.0 is showing up as coming IN from the WAN.
