Multi-WAN Spillover



  • Hello,

    I have been looking the way to setup my pfsense box to have ability to do spillover wan load balancing. I have purchased 2 different ISPs line with different speed. The primary ISP has faster link than others. The current setup I have is basic fail over.

    Sometimes, I found someone on my network is downloading large file to the point that the primary ISP will become so slow. When the traffic on primary ISP is busy, I would like to start using the secondary ISP. I couldn't find a way to do that other than basic fail over. Forget about round-robin because sometimes you are stuck with secondary ISP although the primary ISP is sitting idle. The basic fail over can only sense packet loss and high ping but can't sense the bandwidth utilized.

    I used to configure Sonicwall before and I know they have feature called spillover which when the primary wan reach certain threshold it will start utilizing secondary wan. I know pfsense is not same as sonicwall, but I just would like to know if it has capability to do spillover.

    I have been looking on Google and forum but



  • Bump. I also would like to know if this is possible. Specifically, the ability to do spillover like sonicwall does.



  • no such option exists.

    you could probably solve you issue with traffic shaping



  • I have this same need. Additionally a way to limits the maximum amount of data allowed to use the second WAN port. I have a satellite link with a max monthly limit which also as unlimited data between midnight and 0600 each day.

    I know little about pfsense and just starting my research. I have installed on a VM and starting my learning process. While it does not have a "spillover" capability I am wondering if a combination of gateway groups, traffic shaping, and schedules might not get me there.

  • implementing a spillover (if at all possible) would be a pretty big effort, with probably less 1% of the community that wants/needs it. (i'm making up numbers as i go here)

    unless the demand goes up or someone contributes the required code to get this working, i don't see this happening any time soon.
    It would be a nice feature for all those with metered connections(=sat/3G/dailup), but time is limited for the developers.



  • This thread got me thinking about TOD (Time of Day) applications like the Sat unlimited times and programs like Playon, where you can set a time window for downloading programming.  I would love to find a good method for static routing change implemented say by a CRON job to move traffic between WAN1 and WAN2 then flip it back at the end of that window…

    Any ideas?



  • Using schedules you can switch gateways by policyrouting on a specific date/time

    I know there is a settings inside the firewall where you can configure scheduled based policy and select the appropriate gateway.

    Unfortunately, I live in developed country where the unlimited ISP is far from acceptable (yes, either you are getting crappy speed due too many user or you are paying amount of $$$ that is equivalent to number of Gigabit speed, I meant you are paying thousand grand to get good connection basically). I have to rely on using 3G/4G connection which is hard capped. As far as traffic sharper, it only regulates the bandwidth. But it doesn't regulate to use which WAN link like Spillover would do.

    Thank you
