Please can someone help. Total newbie at this. I have a TP Link VR400 Modem/router with a UsB drive plugged into its port. I have now got a mesh system as the wifi coverage wasn't good enough. I can access my USB drive via ftp local and ftp via internet.

I am trying to access via DLNA for my Quest headset and also by Network Neighborhood (map network drive) on my pc's (all which used to work). I can't get DLNA to work, or map the network drive on my pc. I have googled about port forwarding and "think" I've done it right, but DLnA doesn't work and still can't map the network drive on pc. If I switch back to my old connection on my router, I can access but I don't want to keep switching internet connections, especially for my quest as the wifi signal isn't really strong enough for where I want to use it.

ive attached a screenshot of my settings. I also tried switching the ip address to the wan port address but this hasn't helped either. I have also tried switching the firewall off, on the tp link, but that hasn't helped. Please please can someone tell me what I'm doing wrong. Thanks
