About Firewall Rule Translator

Translates a deliberately small neutral layer-3/layer-4 rule into reviewable nftables, Cisco extended ACL, and Azure Network Security Group text. It exposes the semantic gaps instead of claiming that policy conversion across stateful and stateless platforms is automatically equivalent.

• Generates text only and never connects to a firewall or cloud API.
• Supports a single CIDR source, CIDR destination, protocol, and port or range per rule.
• Leaves Azure priority at a visible starting value and does not invent policy placement.

Frequently Asked Questions

Are the outputs equivalent?

Not necessarily. Platform statefulness, ordering, direction, interfaces, defaults, and object models differ. Treat each output as a reviewable starting point.
