Xg210 Load Balancing setup

Update:

"set routing wan-load-balancing weighted-round-robin ip-family all" in XG console


My speed test increased above 20mpbs but is inconsistent.

Is there a way to calculate what speed I should expect when using load balancing?

How do I know the load balancing is actually working?

Load balancing is simply a method of choosing one of those interfaces. 

This means, it is not "combining" the traffic. Instead it is about "Which interface should i use for this "new" connection.

See: https://docs.sophos.com/nsg/sophos-firewall/18.5/Help/en-us/webhelp/onlinehelp/AdministratorHelp/Routing/Gateways/RoutingLoadBalancingWeights/index.html

In V19.0 you can setup this criteria even more granular by telling the firewall not to use connection based on packet lost.

But from a technical perspective, you cannot get 150 mbit/s. Some speed tests are misleading. They use "Multiple Connections". Means, the firewall can use for connection 1 interface one and connection 2 interface two. This results into "150 mibt/s" but most connections/apps does not work that way. You have one single download and it will "tied to one interface".

So what your saying is that the loading balancing just allows me to chose what interface I want certain traffic to go through?

That is how it works, yes. There are technical challenges, which prevents to work that way you want to use it. The target server cannot figure out, what you are doing by load balancing. This means, it cannot work that way.
