Routers Administrator's Handbook

The IP Subnets screen allows you to configure up to seven secondary subnets and their DHCP
ranges, by entering IP address/subnet mask pairs:
☛ Note:
You need not use this screen if you have only a single Ethernet IP subnet.
This screen displays seven rows of editable columns. All seven row labels are always visible, regard-
less of the number of subnets configured.
❑ To add an IP subnet, select one of the rows, and click the Edit button.
Check the Enabled checkbox and click the Submit but-
ton.
The screen expands to allow you to enter subnet infor-
mation.
If DHCP Server (see “DHCP Server” on page 68) is
not enabled, the DHCP Start Address and DHCP End
Address fields do not appear.
❑Enter the Router’s IP address on the subnet in the IP
Address field and the subnet mask for the subnet in
the Netmask field.
❑Enter the DHCP Start Address and End Address of
the subnet range in their respective fields.
Ranges cannot overlap and there may be only one range per subnet.
❑ Click the Submit button.
To delete a configured subnet, set both the IP address and subnet mask values to 0.0.0.0, either
explicitly or by clearing each field and clicking the Submit button to commit the change.
☛ NOTE:
All additional DHCP ranges use the global lease period value. See page 68.
