Where does the license counter get the IPs from?

Hi,

we recently switched from an appliance to a software licence. Now I'm a little confused where the license counter gets the IPs from.

Whe have several subnets in separate VLANs. For example:
VLAN 100 - 10.0.0.0/24
VLAN 101 - 10.0.1.0/24
VLAN 102 - 10.0.2.0/24

They are all connected to a layer 3 switch, which has an IP address (10.0.x.254) in each subnet an acts as a router between those nets. Of course the clients use the layer 3 switch as default gateway.

The ASG is also connected to the layer 3 switch in a seperate VLAN (VLAN 199, IP of firewall = 10.0.199.1, IP of switch = 10.0.199.254). The switch uses the ASG as default gateway. So all destination IPs that can not be routed internally are forwarded to the ASG. There is no NATing in between.

Now I look at the license counter of the ASG and there is only one IP counted. It's 10.0.199.254.
So where does the license counter get the IPs from? I can see all real internal source IPs in the log files. But they are not counted.

Thanks for your input,
Stephan
