It is still pending for consideration by the software developer. This feature should be implemented in enterprise routers, such as the ER8411. Alternatively, TP-Link may produce a different router...

Typically, Loopback protection is on switches, but for a router? It's good to have.

Well, maybe you could put this request for consideration. It would be better to have the feature available for business/enterprise routers.

Yeap! I support this!

Not only for this model. It should be for all business/enterprise routers!

I think it is good to have this feature!
