Incoming connection on 80 port

[PeterEl]

1) So, probably, better is leave the default settings...

2) Today I noticed a strange thing, when my computer was turned off and no one LAN port is no worked (not light) and no used, and WI-FI is turned off also, the WAN-port (internet) is BLINKED, but not often.

I use DHCP connect to internet - dynamic ip.

Is it normal? that WAN is blinked when i not use internet???? Why it could be?

Thanks everybody fo answers.

It may be perfectly normal , as an example your ISP might want to "know" if the modem is coneected and working, there could be people (not necessarily malicious) pinging/arping/whatever, you may be part of an (ISP assigned) subnet range and get broadcasted packets, and of course there are thousands (or tens or hundreds of thousands) compromised machines/botnets that are randomly pinging/probing the internet for open ports and the like .
