Is the upstream and downstream separate from loadbalancing? for example,
The config is shown as below, there are three WAN links with runing OverFlow load balance algorithm.
WAN1 - LeaseLine (10Mbps/10Mbps)
WAN2 & 3 - ADSL (20Mbps/1Mbps)
Question 1: When WAN2 & 3 fail, does all the packets will route through WAN1 without loss any active session?
Question 2: for example, the upload bandwidth of WAN2 &3 have been used, but WAN1 is avaliable(while the download bandwidth of WAN2&3 are still free). Does the upload packets will go through WAN1?
