Specific Configuration

Network interfaces

The default network configuration (as best can be told) is:

Interface Name	Description	Default configuration
br-lan	LAN & WiFi	192.168.1.1/24
eth0	2.5Gbit port marked WAN ¹	Setup for DHCP (external), not working
lan1-4	Default LAN 1Gbit port	DHCP (internal)
phy0-ap0	Default 2.4GHz Wifi ax/b/g/n	DHCP (internal)
phy1-ap0	Default 5GHz Wifi ac/ax/n	DHCP (internal)

_{* note 1: older OpenWRT 25.12.4, WAN port has not been supported on some device, so the workaround is to move wan port to lanX (one of the lan ports) to the WAN.}

Switch Ports (for VLANs)

Please fill in real values for this device, then remove the EXAMPLEs

Numbers 0-3 are Ports 1-4 as labeled on the unit, number 4 is the Internet (WAN) on the unit, 5 is the internal connection to the router itself. Don't be fooled: Port 1 on the unit is number 3 when configuring VLANs. vlan0 = eth0.0, vlan1 = eth0.1 and so on.

Port	Switch port
Internet (WAN)	EXAMPLE 4
LAN 1	EXAMPLE 3
LAN 2	EXAMPLE 2
LAN 3	EXAMPLE 1
LAN 4	EXAMPLE 0
