3 different network segments into one FS

[kaisersouse]

Once again I am asking for help. We have 3 network segments: 192.168.100.x, 101.x and 102.x. These addresses are handed out by the AP and this cannot be changed. We have disabled DHCP on the FS server. We need these addresses to go from the AP into the FS server for billing.

The FS servers internal network address is 192.168.110.2. The APs internal address is 192.168.110.1

Firstspot will be used only for billing and session time tracking. DHCP is off, NAT is off, Client Isolation is off. They must stay off.

PLEASE tell me how the "Multiple Network Segments" tab should be configured so that FS will see these network segments. Currently on the AP we have 1:1 NAT configured as such:
masq 192.168.100.0/24 to dev ether2
masq 192.168.101.0/24 to dev ether2
masq 192.168.102.0/24 to dev ether2

On our AP controller:
ether1 = connection to Cisco 2620 router (outside internet)
ether2 = connection (crossover cable) directly into FS server private card

On FS server
public = connection to Cisco 2620 (outside internet)
private = connection to ether2 on wireless controller

Our dispatcher is configured currently:
Private IP = 192.168.110.2
Subnet = 255.255.255.0
DNS Server IP = 12.127.16.67

This is running FS version 3.1.4

Please do not tell us we need to upgrade. This should be working. I need to know how to set up the "mulitple network segments" tab. I would really like a specific example.

Thank you.
