A Go library that wraps the iptables command-line utility, providing functions to append and delete rules and to create, clear, and delete chains. It exists because in-kernel netfilter lacks a good userspace API, so programmatic manipulation is best done via the iptables tool.

Use cases

• manage firewall rules from a Go application
• programmatically add and delete iptables rules
• create and clear custom iptables chains
• build a Kubernetes CNI or network policy controller
• configure Linux packet filtering in Go

When to choose

• you need to manipulate iptables rules from Go code
• you want a maintained wrapper instead of shelling out to iptables yourself
• you are building networking software on Linux that needs firewall control

When to avoid

• you need nftables-native or eBPF-based packet filtering
• you are not on Linux
• you need a high-level firewall management UI rather than a library
