failed TCP/UDP checksum en reverse ICMP failed

[Verwijderd]

Ik krijg ineens allerlei rare errors op mijn Freesco router:

kernel: MASQ: reverse ICMP: failed checksum from [80.137.xxx.xxx]!

en

kernel: MASQ: failed TCP/UDP checksum from [80.3.yyy.yyy]!

Iemand enig idee wat dit inhoud? Heb wel gesearched maar daar kwam niet echt een definitief antwoord uit.

10) Why do I get the log message "kernel: MASQ: failed TCP/UDP checksum from xxx.xxx.xxx.xxx!"?

This is due to a damaged packet arriving at your machine. This packet didn't quite make it intact across the Internet / your network and the router sees this and tells you. There is nothing you can really do about it and it doesn't cause any problems. It is not a sign that someone is hacking your computer. If you frequently gets lots of these messages, it may mean that you have some bad network cabling or a bad Internet connection.
