Hi all,
I am trying to set iptables for the BBB, following a tutorial.
Almost all the commands with iptables work, but when I try to run this command:
iptables -A INPUT -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT
or this older version of the same command:
iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
I get the following error
iptables: No chain/target/match by that name.
I googled the error and found that this could be the cause
No connection tracking support in the kernel
CONFIG_NETFILTER_XT_MATCH_STATE is not enabled in your kernel config.
CONFIG_NF_CONNTRACK is not set
I think that being able to use the complete functionality of iptables could be great for all the users trying to connect their BBB to the internet.
Is there anyone who can help me, please?
