Posted: Tue Mar 14, 2023 23:54 Post subject: FireTv on Virtual Access Point + Plex = No Connect
I'm stumped, and I don't know if this is a dd-wrt issue. I have a FireTV Stick. For my home network, I created a VAP for devices that I don't want talking to my NAS or each other. The FireTV connects to the VAP, no problem. I have Plex on my NAS, no problem. I can connect to my Plex server from any browser on or off my network. I can connect using my Android phone or my car, on the home network or not. No problem.
The FireTV Stick will not connect to the Plex Server. I am suspecting that there is something blocking a connection from 192.168.32.0/24 to 192.16.16.0/24. (The .32 network is the VAP).
Anyone have any ideas? Maybe this a Plex setting issue, but I've exhausted my ideas and of course Plex is useless with their help files. _________________ Netgear R9000

Wifi doesn't behave well with multicast traffic. I forget if this setting is also available for VAPs, but I do recall seeing it for the main AP interface in the webUI. This could be part of the problem (or not). _________________ "Life is but a fleeting moment, a vapor that vanishes quickly; All is vanity"

Not sure if your trying to access plex over local LAN assume you are, so providing your firewall is allowing you access from FS to NAS subnets, but if your using a Qnap NAS you'll need to add IP range in allow/deny list, Control panel>Security>Allow/Deny List, may be similar in other makes.

Another thing to look at is if you connect to your plex server via its domain name (it will use NAT redirect/hairpinning) then the return traffic is going directly to your LAN client.
Recently DDWRT has begun to use rules to block INVALID traffic and this kind of asymmetric traffic, although perfectly legitimate, is also DROPped by these rules.
I have requested (and made) a patch to have a setting for the INVALID rules but it was turned down.
Thanks everyone. I have some tweaking to do, and some experimenting to try.
I solved the problem by disabling all setting on the virtual interface and then trying the settings one at a time. Yes, it took a while. What I found was I need Masquerade / NAT enabled. I'm not sure why; I have more reading to do. _________________ Netgear R9000

Without Masquerade/NAT you should not have Internet Access
Thank you. I did not realize what the setting did, and that explains the issues I was fighting with. Too bad the default value is not shown next to many of the DD-WRT settings. _________________ Netgear R9000
