Can action=redirect be used in NAT chain src-nat?

The use of action=redirect in the NAT (Network Address Translation) configuration is specific and has particular applications. In NAT, specifically within the src-nat chain, the primary purpose is to translate source addresses of outbound traffic, allowing internal IP addresses to be mapped to a single public IP address.

The action=redirect is intended for use in the filter chain, typically utilized for transparent proxying scenarios where traffic is redirected to a local service or a cache server on the router. This is most commonly applicable to NAT's dst-nat (destination NAT) chain, where incoming connections are redirected to specific internal resources based on the destination IP and port.

Using action=redirect in a src-nat context does not align with its intended function, as source NAT does not deal with rerouting incoming traffic to different destinations but rather modifies the source address of outgoing packets. Therefore, asserting that action=redirect can be used in the src-nat chain is incorrect, making the statement false.
