Enable Multi-WAN Failover for EG105GW(T)

We need to eWeb to the local device and change the settings to enable multi-WAN failover

1. Click the device and select eWeb

2. Click "Create Tunnel"

3. Choose the Local device (EG105GW(T))

4. Go to Network > WAN

5. We will change the port type from LAN to WAN to enable a second WAN port

6. We will have 2 WAN ports, WAN0 and WAN1. Select DHCP and click Save

7. Go to Load Settings and Select Load Mode and click Save

Load Balancing - Traffic will be shared between the 2 WAN links, which means both links will be active. We can set the traffic sharing between the 2 links. The traffic will be spread across multiple links according to the weight of each WAN port. For example, if WAN0 and WAN1 weight are set to 3 and 2 respectively, 60% of the total traffic will be routed over WAN0 and 40% over WAN1.

Active/Secondary - Only the Primary link has traffic and the Secondary link is for failover and will be active if the Primary fails. All traffic is routed over the primary interface. Once the primary interface fails, traffic will be switched over to the secondary interface. If there are multiple primary and secondary interfaces, please configure their weight (See balanced mode).

8. Select Load Balancing Policy - by default choose Smart Load Balancing

9. For Active/Secondary load mode, set the primary and secondary interface and click Save

10. Go to Line Detection. This is to monitor which link is active and will initiate the failover. Go to Action and edit the settings based on your preference.

11. When you click Edit, you can configure the link monitor. The link monitor determines if the link is online or offline. After the multi-WAN feature is configured, each WAN port will be designated to ping the the detected destination IP address at a regular interval (default detection interval: 5s). If multiple detected destination IP addresses exist, each IP address will be detected. As long as the ping test initiated for one IP address is successful, the detection result of this round is considered to be valid. If the current detection status is offline, the detection status will change to online only if the number of the ping tests for an IP address is equal to that of the required rounds for going online. If the current detection status is online, the detection status will change to offline only if the number of the ping tests for an IP address is equal to that of the required rounds for going offline.

Detection Interval - This is the time for 1 Round. Below is set to 5 seconds, so 1 Round is 5 seconds.

Rounds for Going Online - This is the number of rounds before a link is considered Online. Below is set to 8 rounds, 1 round is 5 seconds so 5 seconds X 8 rounds = 40 seconds

Rounds for Going Offline - This is the number of rounds before a link is considered Offline. Below is set to 3 rounds, 1 round is 5 seconds so 5 seconds X 3 rounds = 15 seconds

You can adjust this setting to make it switch faster or slower and below is the default settings.
