Been following http://forum.mikrotik.com/t/using-routeros-to-vlan-your-network/126489/1 and building a config based on the guest example adapting it to also include a work isolated network.
This config: https://forum.mikrotik.com/download/file.php?id=46392
I notice it is using ether1 for wan.
# Yellow WAN facing port with IP Address provided by ISP
/ip address add interface=ether1 address=a.a.a.a/aa network=a.a.a.0
/interface list member
add interface=ether1 list=WAN
Isn’t ether1 the 2.5gbit PoE port on the hAP ax3?
Would it be better to use ether5 as the wan interface leaving ether1 available for LAN?
is it a simple as changing the config to reference ether5 instead of ether1 or would additional config be required?
