I know this is an old thread but I don’t want to make a new one as I think the answer is on the forums somewhere, I just can’t find it.
I have tried to assign an Access VLAN to the ‘untagged’ lan but I lose all contact with the router. I already have wifi turned off and none of the ports allow access to my laptop, the one I used to make the changes.
I have to reset the router and change the setting so that there are only 3 Access VLAN ports and leave the ‘untagged’ port alone.
I assume it has something to do with the ‘untagged’ port being the IP address of the router and also being port one?
My problem is I’m afraid to use Port One now because I believe it can see every other device (maybe this is necessary for the router IP address port) so can anyone please give me any advice how to secure the ‘untagged’ port so inter vlan is disabled and it can’t see any other devices apart from obviously the WAN port I imagine?
Although I did notice in the WAN port settings there is a VLAN option but I am not even going to try messing with that when I can’t configure the LAN ports correctly.
Why would a WAN port be VLAN if the nature of WAN means it has to communicate with every device connected to the router?
Thanks for any advice.
Kind regards.
