Inbound connection?

on my comodo firewall i had tree inbound connections. They were UDP IN. I was wondering if this is safe???


It depends on what application is using the inbound connection. They can be dangerous of course, because it is a connection from the Internet connecting to your PC.
Are you running any P2P apps? Any file/printer sharing in your LAN?

i was running u torrent. If Im am done with u torrent should i disable the inbound connection if it still exists?

If you uninstalled uTorrent, sure delete the rules for it.
If you just shut it off and intend to continue using it then keep the rule.

When uTorrent is shutdown then the firewall blocks the port automatically.

Because there is no App listening on that port your torrent stragglers will be
blocked and show as windows operating system in the firewall logs.
