I have an OpenWrt Router (Archer C7 v2) that delivers two Wifi networks:
HOME (192.168.1.254/24) and GUEST (192.168.2.254/24).
HOME belongs to the main network with the internet gateway + DHCP server (192.168.1.1) and DNS (192.168.1.2).
GUEST is only reachable over Wifi and the routing and firewaling is done in the OpenWrt router.
The router uses the internal DHCP server for GUEST Wifi.
This works without problems.
Now I want to extend the Wifi range with additional OpenWrt devices.
I was able to do this with the HOME network and 802.11s mesh nodes but it seems problematic to route GUEST over the same mesh.
What is the easyest working solution to realize this?
Create a new firewall zone GUEST, allow forward to WAN.
Create a new interface GUEST, static IP, and specify gateway as the router itself. setup a new DHCP server for it.
Create new wireless mesh GUEST and assign it to the GUEST interface.
You must also do the same on the AP, without the DHCP server of course.
On the AP, setup an wireless network, and assign it to the GUEST firewall zone.
Oh ? You have HOME computers also on the AP ? I was assuming the AP was only for the GUEST.
I agree that two mesh networks may be too much,
Have you consider using wires to connect AP to router ? If so the answer is to use VLAN to separate traffics.
@uweklatt Also using batman here. So one 5Ghz (fast) mesh backhaul ssid interconnects both APs and is able to give the "only wireless" AP access to many VLANs. the Second AP can then bridge the bat0.x vlan if to new AP ssids , preferably on 2.4 ghz radio.
