LAN IP Alias allows Vigor Router to own multiple LAN IP addresses in a single subnet. Each IP address can be a gateway mapping to a specific WAN interface. So LAN clients can go through a different WAN interface simply by changing their gateway IP on the PC.
This is useful when you have more than one ISP, and some websites/services have better performance when accessed via ISP1, while some others are better via ISP2. When connection quality depends not only on the ISP but also on which server/websites the LAN client is connecting, the LAN IP alias allows the LAN client to choose their desired Internet gateway based on the user experience.
To set up the LAN IP Alias on Vigor Router:
1. Go to LAN >> General Setup page, click Details Page for the LAN profile.
2. Click on LAN IP Alias button.
3. Configure LAN IP Alias settings on the pop-up window:
4. Vigor Router now has two LAN IP addresses in the LAN subnet, and the LAN clients can easily choose which WAN interfaces they would like to go through by changing the gateway setting on their computers.
