Setup WAN as LAN interface [ Lyra (MAP-AC2200) ]

Hey there,

I am using an ASUS Lyra (MAP-AC2200) which only has two ethernet ports. They are not colored or have any specific label indicating which port is lan or wan.
OpenWRT assigns the eth1 port ( the port next to the power cable input ) to lan and the other port eht0 to wan.

Regarding to the Lyra (MAP-AC2200) Openwrt Wiki setup page ( ):

It has one 1G LAN port and one 1G WAN port, with six internal antennas.

I want to know if I can use that WAN port as LAN port and what is the proper way on how to configure that?

My thought were to

  • simply put eth0 to the LAN zone or
  • bridge eth0 and eth1 and removing the whole wan section in /etc/config/network
    • For example:
config device
	option name 'br-lan'
	option type 'bridge'
	list ports 'eth1'
    list ports 'eth0'

config interface 'lan'
	option device 'br-lan'
	option proto 'static'
	option ipaddr ''
	option netmask ''
#	option ip6assign '60'

#config interface 'wan'
#	option device 'eth0'
#	option proto 'dhcp'

#config interface 'wan6'
#	option device 'eth0'
#	option proto 'dhcpv6'

Yes, you can (via bridging).
