How are multiple WANs handled?
WANs are treated completely separately, however the same set of rules are evaluated on all traffic. The bandwidth settings of each WAN must be set correctly and independently, but there is no need to maintain separate rule sets beyond that.
Why is my internet slow when I enable QoS?
Likely because your WAN bandwidth settings are too low. Verify your settings for WAN Bandwidth are correct.
QoS is not helping my high priority applications. Why?
This is likely because your WAN bandwidth settings are too high and QoS is having no effect or you simply do not have enough bandwidth to support your high priority applications regardless of low priority traffic. Verify your settings for WAN Bandwidth are correct.
Why do custom rules only match bypassed traffic?
Non-bypassed traffic is handled differently because it goes through the Untangle network stack - not the normal linux packet flow. You can use the Bandwidth Control application to assign priorities to non-bypassed traffic.
Does QoS work on non-WAN interfaces?
No, only WAN interfaces have limits and are subject to QoS manipulation. If you have a DMZ with local servers all communication between that network and the internal network is not subject to QoS.
Can I limit users to specific speeds, such as 5k/s?
You can modify the QoS Priorities table to limit a priority to a certain percentage of your overall line speed, then assign that priority to a user or several users. Please note the bandwidth limits will be shared for the entire priority, so this solution does not scale to many users.
Does QoS work with PPPoE interfaces?
Yes, but many PPPoE connections have comparatively low bandwidth so QoS may not be very effective.
