    Default Time based wan balancer traffic allocation

    We are a K-12 school and have 3 x connections in WAN BALANCER.

    We are probably going to move one of these to a faster connection with an ISP that does an education special.
    Doubles our speed and halves the cost so it's very attractive option

    Trouble is that this will be a 250Mbit connection until 4pm after which it is shaped to 25Mbit and unshaped again at 4am

    Our other 2 connections will remain as 100Mbit 24/7.

    So after 4pm/4am we'd like to schedule a change in the WAN BALANCER traffic allocation percentages.

    Any ideas how to achieve this ?

    Thanks,
    Phil

    It isn't probably elegant, but you could have two nearly equal policies: one with Wan Balancer working through the 250Mb, the other not. Then, in Policy Manager you can have rules based on the time of day. If it's daytime, go to the 250Mb policy else to the other one.

    Thanks, but not sure I get your solution. Wan Balancer is a service app that doesn't work at a rack level so policy manager can't help ?

    You'd need to tune your priorities.
    https://wiki.untangle.com/index.php/QoS

    For example use the top 4 for the 250Mbit, and the bottom 3 for the 25Mbit.
    Then use the two different racks for different bandwidth control rulesets. During hours map everything to the top 4 priorities, after hours map everything to the bottom 3 priorities. This would only work for non-bypassed traffic though.

    Thanks, we had another thought on how to achieve the result we need. We are OK to basically mark this connection as down in the wan balancer once it is limited. So was thinking of adding a custom iptables rule via ssh on a schedule that blocks connection to 8.8.8.8 (used as the connection test ip). This would mark it as down in the balancer and prevent new connections being sent to it ?

    Something like

    iptables -I OUTPUT -p icmp --icmp-type echo-request -s WANIPof250Mbit -d 8.8.8.8 -j DROP
