We have just got an ATP800, and thrilled with it, but I'm still having issues with L2 isolation between physical ports.

Our current config port wise is:
Core | Peplink | VPN_Link |Workshop| CCTV| Wi-Fi | Pr_Failover | ZUKU|ge9|ge10|ge11|ge12|ge13|ge14

I want to isolate Wi-Fi, ZUJU, Workshop and CCTV, From Core. e.g. traffic from these networks should not cross into Core other than for the allow list.

As I understand things, putting 'Wi-Fi, Workshop, CCTV' into the member's list should be sufficient, possible for confirmation and correction if required, I have attached some picks which should explain.

I have read various Zyxel documentation on this, but it seems I'm missing something.

Thank you in advance. :)

    Hi @cfts_ea ,

    The "port" you configure is layer 3 IP interface.

    So that you need to set interface Core to a ZONE(Object > ZONE), ex: Core ZONE.

    And interfaces Workshop/CCTV/Wi-Fi/ZUKU into another ZONE, ex: ZONE1.

    And then go to Security Policy > Policy Control to add rules,

    rule1: From ZONE1 to Core, src: any, dst: address group of allow list, service: any, action: allow

    rule2: From ZONE1 to Core, src: any, dst: any, service: any, action: deny.

    Sorry, and thank you, I only just got back to this I'd setup a Raspberry Pi, to do this, and will now look at seeing if this function can be implemented in the ATP, with the above info :)
