Configuring Local Subnets

ZoneFlex Access Points can be configured to provide routing/network address trans-
lation (NAT) functionality by using the Local Subnets feature. When a Local Subnet is
enabled, the standalone AP serves as a gateway router with the ability to manage its
own subnets, providing DHCP server and DNS cache functions for both wired and
wireless clients. These clients can be assigned private IP addresses from a user-defined
address pool. Traffic from the client station in private address space appears on the
outside as if generated by the AP itself. In this way, the AP performs Layer 3 packet
forwarding not only for Hotspot/WISPr usage, but for standard usage as well.
Up to four IP subnets can be configured per AP, each with its own address range which
cannot conflict with one another.
To configure a local subnet for router mode support
1. Go to Configuration > Local Subnets. The four tabs at the top (Local Subnet 1 -
4) allow you to configure each of the four subnets independently.
2. Click Enabled next to Subnet. The local subnet configuration options appear.
3. In Local IP Address, enter an IP address for the gateway. The default address for
Subnet 1 is 192.168.40.1. This address can be used to access the AP's Web
interface for configuration and monitoring from devices connected to this subnet.
4. In Subnet Mask, typically you would want to leave the setting at its default value
(255.255.255.0) for a Class C subnet with an address pool of up to 254
addresses. An error appears if you enter an invalid IP/netmask combination.
5. In DHCP Server, click Enabled if you want to enable DHCP for this subnet. Starting
Address and Maximum DHCP Users fields appear.
6. In Starting Address, enter an address in the same subnet as the Local IP Address
(e.g., 192.168.40.2).
7. In Maximum DHCP Users, enter the maximum number of clients that can be
assigned addresses by DHCP in this subnet (valid values are 1-253 if the default
subnet mask is used).
8. In Access VLAN, enter a VLAN ID to segment client traffic arriving from this subnet
from other network traffic. (Example: if you use the default 192.168.40.1 address
range, you would generally want to use "40" as the VLAN for this subnet.)
9. Click Update Settings to save your changes. The local subnet is created imme-
diately and can now be applied to WLANs or Ethernet ports from their respective
configuration pages.
