Hi
I ran a quick port scan with Nmap and I found out such a port 514 filtered shell.
Could you please tell me what it is about and if I should do something with it?
Thanks
Ok,Port 514 is https://en.wikipedia.org/wiki/Remote_Shell - your ISP likely filters it to prevent insecure services.
The fact that all your ports aren't filtered though suggests you have an improper firewall setup.
You seems to like making fun of users here rather than giving useful answers.If someone say "Remote_Shell" is not the same written "remote" somewhere...
Is clear than "remote" on logs has nothing to do with any firewall rule or opened services inside routerboard...
if you open "remote" is just a "remote" server where the log must be sent (syslog)
If you do that question, probably your firewall is a mess.
You use random tools without understand for what are for, and probably copy & paste rules everywhere from web or youtube, etc.
If you keep DEFAULT rules on the RouterBOARD, the firewall is already well configured...
