Redundant Internet connections on consumer hardware with OpenWrt and Mwan3
Load Balancing is Standard
In configurations with multiple network interfaces, Mwan3's default operating mode is to perform load balancing. If you don't want Mwan3 to perform load balancing, replace the value balanced with WAN_WAN2 in the rule paragraphs at the end of the /etc/config/mwan3 file (Figure 5). The WAN_WAN2 setting means Mwan3 will only use WAN2 in cases when the first interface WAN1 is offline.
Figure 5: The rule entries in the Mwan3 configuration determine how Mwan3 routes packets.
Conclusion
If you think you would benefit from the load balancing and redundancy of a dual uplink configuration, or even if you just want to experiment with new tricks on an old home router, download OpenWrt and get started with the Mwan3 extension.
