Client wifi isolation - broadcast packets getting through

[stupot99]

On a 7800DX with FW 2.32b.

I've noticed that broadcast packets, sent from a laptop connected to the router via wifi (on a guest/virtual access point with clients isolation ticked), are turning up on a pc connected to router via an ethernet cable.

I assumed client isolation meant that there would be no traffic between isolated clients and the rest of the LAN, but this isn't the case. Maybe this is by design for broadcasts.

Is this a problem?

You need to create a 'Interface Group' for your 'Guest Network'

Example

1. Click on Interface Grouping
2. Click on 'Add'
3. Enter a 'Group Name' eg guest
4. Under 'Available LAN Interfaces' select your 'Guest Network' and click on the arrow pointing left, so the guest wifi network should now be added to 'Grouped LAN Interfaces'
5. Click on 'Apply'
6. Under 'Group Isolation' tick the box and click on 'Apply'
7. Click on 'LAN >> Ethernet'
8. Under 'Group Name' select your guest wifi group for this example I used 'guest'
9. Tick 'LAN Side Firewall' and click on 'Apply'

That should be it, the guest wifi network should be totally isolated.

Thanks that worked.

Aha, the wifi Client Isolation means isolation from each other, not isolation from everyone.

Thats right, it means wireless isolation on the same SSID

Thanks, good to know how to do it right

Menus really need to have some explanation available, as translation is far from perfect
