Nfqueue bypass option skips the enqueue of packets to userspace if no application is listening to the queue. https://wiki.nftables.org/wiki-nftables/index.php/Queueing_to_userspace If this flag is not specified, and for example the daemon dies unexpectedly, all the outbound traffic will be blocked. Up until now we've been using this flag by default not to block network traffic if the daemon dies or is killed for some reason. But some users want to use precisely this behaviour (#884, #1183, #1201). Now you can configure it, to block connections if the daemon unexpectedly dies. The option is on by default in the configuration (QueueBypass: true). If this item is not present in the daemon config file, then it'll be false. |
