| ipset is designed to store multiple IP addresses in a single collection, while being performant and easier to maintain. Common usages of ipset include storing large amounts of IP addresses or ranges in a single set as well as conditional routing by domain. As routing ultimately works at the IP layer, being able to use ipset with domain based policies is useful for many websites or services which use multiple IP addresses or large Content Delivery Networks which means the IP address of that domain is constantly changing, individually adding these IP addresses would become unmanageable very quickly, ipset can help maintain this for you. | ipset is designed to store multiple IP addresses in a single collection, while being performant and easier to maintain.

| + | |||
| + | Due to the default firewall (fw4) now being based on nftables (rather than iptables), the ipset functionality commonly used in conjunction with dnsmasq and mwan3 no longer works in 23.05 releases. This is due to mwan3 not being fully compatible with nftables and requiring iptables compatibility/ | ||
| + | |||
| + | You will need to use nfset with dnsmasq for ipset polices to be created, which mwan3 only supports at this time. mwan3 currently does not support nfset in rules directly, hence the need to create ipset policies. | ||
