A question about "direct.xml" file.

Hello, I removed all rich rules, but "direct.xml" file has below lines: <rule priority="0" table="filter" ipv="ipv4" chain="INPUT_direct">-p tcp --dport 80 -m state --state NEW -m recent --set</rule> <rule priority="1" table="filter" ipv="ipv4" chain="INPUT_direct">-p tcp --dport 80 -m state --state NEW -m recent --update --seconds 60 --hitcount 30 -j REJECT --reject-with tcp-reset</rule> Why? Could below lines cause drop any connection to server? <rule priority="0" table="filter" ipv="ipv4" chain="INPUT">-j NFQUEUE --queue-bypass</rule> <rule priority="0" table="filter" ipv="ipv4" chain="OUTPUT">-j NFQUEUE --queue-bypass</rule> For example, I can't SSH to server. Thank you.
