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

The use of action=redirect in a NAT configuration is specifically designed for scenarios where traffic needs to be redirected to a different port or destination IP. This feature is typically utilized in the prerouting chain where traffic is initially processed, allowing for redirection before any further processing occurs.

In the context of the src-nat chain, action=redirect can indeed be used effectively. When src-nat is applied, it modifies the source address of outbound packets, and using redirect allows for capturing and directing the traffic accordingly. This is useful for scenarios like transparent proxies, where you might need to redirect HTTP traffic seamlessly without requiring a specific configuration on the client's devices.

Thus, being able to apply action=redirect in src-nat allows for greater flexibility and control over how outbound packets are handled, fulfilling the needs of various network configurations and routing scenarios.
