Router logs am i in trouble? Advise please

[#1]

Below are logs from my router I have however removed my ip. Are these alerts something i have to work about. I can see no changes to my network. Has my router kicked them out and are there any changes i need to make.
Regards Podman

It's probably just a log of an attempt to gain access however it depends on the make and model. To put it bluntly if some little chineese person who doesn't understand english terribly well wrote it then intrusion could mean attempted intrusion! On the other hand if its a router made in the west... you're probably in trouble.
Would be a wise idea to post the make and model of router so some of the experts here can look into it for you. Also ensure that you have firewalls installed on all PCs on your network. Most routers do have their own firewalls but thats only one line of defence. If a hacker gets past it you're stuffed!

It's nothing - just a few failed attacks over several hours, from different sources.

I think the fact your router has detected the potential attack and reported it in the log is a sign that its firewall is doing its job.
