ZyXEL and mixed NAT non-NAT LAN Subnets
Note: This config takes you away from the standard automatic configuration that the AAISP TR-069 servers will configure your router with. This means, once you made these 'custom' configuration changes to your router if you then instruct the AAISP systems to send configuration to your router then your settings will be over written.
This will describe how to set up your ZyXEL so that you have two LAN subnets - a private one and a public one. You can have youe normal devices in the 'Main' LAN on a 193.168.1.x subnet, and then statically configure some servers with public IP addresses assigned by AAISP.
