@GeneraalSpeknek, sorry if I'm missing it, but what's the test switch profile look like. It should have the test (99) vlan as the native vlan and untagged member.

@Kimberley_j87 then if the WAN Port is connected to the ONT, it should work. If you have a techie friend, it might be time to bribe them with a 6-pack for some help.

@Kimberley_j87, lol... to to be specific... Router(Garage) LAN Port -> Cable that goes from garage to Lounge Internet Port -> Lounge Internet Port -> Cable -> Switch(Lounge) -> (Cable -> Device)x4

Je vous en prie @Yann77. Splunk is not my area of expertise, but I am sure it can be done. Try posting that in a Splunk forum.

@GeneraalSpeknek, short answer is I think you're replacing the default vlan with the test vlan. Both need to talk between devices. See this guide, it should help....

Sorry, reading on my phone and didnt see properly. 😣
