What's the difference between Allow/Limit + Deny/Block?

[laeg_]

I've installed ufw and gufc front end and there doesn't seem to be any explanation explain the difference between allowing a port and limiting it - blocking it and denying it.

Limit is obviously less than allow but when selected there are no options to set exactly how it's limited so I've no idea what it's actually doing.

Perhaps someone here knows?

Thanks

To be honest I suggest you stop and learn iptables.

Takes as long to learn iptables as it does the various gui tools, and once you understand iptables you will find the gui tools all make sense.
