PS: Merging WAN Connections to combine the throughput is technically not possible.

As you communicate with two different IPs, likely most TCP connections will drop your connection, if you start to load balance between both connection.

So you can load balance but XG will use some sort of sticky connection.

Here is the math behind it: https://docs.sophos.com/nsg/sophos-firewall/18.0/Help/en-us/webhelp/onlinehelp/nsg/sfos/concepts/LoadBalancingWeights.html
