How to increase DHCP IP address range to 500+


I need to increase the IP addresses to 400-500 on RUTX12 and RUTX08 instead of 255 for public WiFi.

Please advise on how best to configure the devices to accommodate increased IP addresses.

Thank you

set your LAN interface to e.g.:
Subnet Mask

and your DHCP server to:
Start IP:
End IP:
Std.-GW to
DNS to

Tis is one of many ways to achieve what you want.
A subnet calculator like this one might also help.

To customize your mask, simply click on “–Custom–” and begin typing the required mask.


Best regards,
