Would like to try dual WANs using mwan3 on my old TP-Link 1043ND v1.6 router.
Fresh install Openwrt 18.06.5, setup wireless,
- add vlan 3 to LAN1 port under network - switch
- add interface wan2 and assign to wan firewall zone under network - interface
then plug in the WAN cable to either WAN or LAN1 port and both able to access internet.
Problem starts after assign metric 10 to wan & 20 to wan2, cannot access internet anymore.
Any help on this pls? (not even install mwan3 yet!)
