# `RedirExpression` type

RedirExpression represents an nftables expression for redirecting packets. This is a specialized form of Destination NAT (DNAT) where the destination address is changed to the local machine's address, often used for transparent proxies.

## Fields

| Field Name | Description |
|---|---|
| `registerProtoMin` - [`NftRegister!`](https://wartiva.com/api-docs/types/nft-register.html) | The register holding the minimum protocol port for the redirection range. |
| `registerProtoMax` - [`NftRegister!`](https://wartiva.com/api-docs/types/nft-register.html) | The register holding the maximum protocol port for the redirection range. If only one port is specified, this might be the same as 'registerProtoMin' or not used. |
| `flags` - [`[NftNatFlag!]`](https://wartiva.com/api-docs/types/nft-nat-flag.html) | Flags that modify the behavior of the redirection operation, such as randomization or persistence. |
