My first post in this forum.
Trying to help a friend with an Edgerouter X for failover.
First time I'm configuring this with OpenWRT.
- Two Wans (wan and wanb) with 10 and 20 metric.
- Both get IPs from the "modem": wam: 192.168.15.X. wamb: 192.168.0.X
- The "modems" get the valid IPs and both has DHCP servers.
- I only edited the /etc/config/mwan3 changing the only instance of "balancing" to "failover"
But that seems to be not enough as if the wam cable is pulled the wanb do not assume the traffic...
Trying to follow this:
https://openwrt.org/docs/guide-user/network/wan/multiwan/mwan3_install_without_luci
Bellow is the troubleshooting report produced by Luci via Status-> MultiWAN Manager -> Troubleshooting:
