curious ip address

Hi,

I see weird errors in the logs and also communications from the modem to ip addresses that I don't understand.

Thanks for your help.

They are bot IP addresses that scan random IP addresses to build a data base of devices that can potentially be hacked.

You should not have the SSH port on the public internet. Turn on the firewall features of the router.

You're being scanned by bots.
What I do is shift ssh to a different port and then more the FW port as well to allow the access.

If you leave ssh on port 22, regardless of the plat form, you will be probed continuously.

Cheers,
John

I had the same SSL errors, updated the FW, problem gone.
How did you turn off your ssh and ftp?

The GSM errors look like a loose SIM card to me.
