@3DScanSTL i use controller so i don't know how it is in stand alone that you use, but all port forwards go lightning fast.. there is no delay at all.

@3DScanSTL remove port trigger config, you only need virtual server

@3DScanSTL hard to say since you haven't shown any screenshots of your configuration.

@dadziuk OK, that's the same version I'm using, I haven't had the problem in a while so I don't know what it could be-

@dadziuk yes I had the same problem with my ER8411, but it's been a few controller versions since, I don't remember which version, as far as I remember I had to start and stop the controller to fix...

@Bonfigleo It probably has nothing to do with it, but I use Initiator Mode on both routers.
