EE Brightbox on Fiber to Junction box

[Numb-nuts 1]

Today I nearly tore my remaining hair out at the roots. It was the very first attempt at an EE brightbox router with a fiber connection.

Port checking tools reported the port as open and then not and then some open and some not. Being my first attempt I read the EE brightbox port forwarding guide and it all made sense to me, so I followed their recommended procedure exactly

Did it work? Not abit of it....

Finally after fartars*ng around all day I realized that it would not allow a computer logging into the router to return through the router. So effectively I required a LOCAL settings for the remote client software using the local IP of my DVR and a second set of settings (for remote use) from outside of the LAN and using my DDNS Hostname.

 

I don't think I have experienced this before so I thought I'd report it in case anyone else is confused about whats happening.

 

Does anyone know if there is a setting that should be changed to allow remote access when logged into the same network?

I couldn't see anything obvious...
