I have a guest and private WIFI setup. Customer wants the guest WIFI going out the backup internet connection.
Can I do this with NAT Mode on the WIFI SSID? I tried putting the 10 network on traffic shaping but it told me that isn't a configured subnet.
If not I will setup a VLAN and bridge it to the MX and do it that way, was just curious if this can be done with NAT Mode on WIFI.
it all nat to the adres of the AP. so you need to add the ap addresses at preferences to wan2. (i guess your mtunnel will also go traverse wan2)
Best way I can think of to accomplish this would be to use a dedicated VLAN and subnet for the guest wifi. Then setup Security Appliance>Traffic Shaping then Flow Preference and Internet Traffic then setup the source subnet as the guest VLAN and protocol, destination, etc as Any and select the preferred WAN1 or WAN2 to direct the traffic.
As @Adam said, you need a dedicated VLAN and use traffic shaping to point that VLAN towards your WAN2.
