Hello, we have a Fortigate 60E firewall connected to a Vodafone HG659 modem which then connects to a 1Gbp UFB connection.

Has anyone else noticed poor throughput with a configuration like this ?

I am thinking it is due to the Vodafone HG659 not being able to handle all the sessions coming in from the Fortigate ?

I am wondering how many simultaneous sessions a modem like this should be able to handle.
