Werner Posted April 8, 2023 Share Posted April 8, 2023 There is not. Install iptables or nftables or a framework like ufw via apt that makes use of either one of those. 1 Quote Link to comment Share on other sites More sharing options...

Werner Posted April 8, 2023 Share Posted April 8, 2023 This can only be answered by you since you are responsible for the security of your device so decision is yours if firewalling is necessary. 0 Quote Link to comment Share on other sites More sharing options...
