Hi Everyone,

We are planning on rolling out a wireless network that can cater for up to about 1000 connections. I'd like our Mikrotik router to act as a DHCP for the Ubiquiti wireless network, but I have no idea how to configure the IPv4 DHCP Server to handle more than one subnet because obviously we're going to need more the a standard /24 subnet allows. I plan on having a lease expiry of about 5 minutes because most users will be just using it quickly to check their email/facebook accounts.

An overview of what I plan on doing is as follows:

WAN Fibre connection > Ether1
WAN Fallback > Ether2
Our internal network is > 192.168.100.0/24 > Ether6
Ubiquiti Devices will be on: 10.0.10.0/24 > Ether3

How do I allocate multiple DHCP ranges to the Ether3 port so when the IP range for each is exhausted then it automatically starts using the subsequent ranges? Should I use 255.255.252.0 subnet? Does that introduce a heap of other issues?

Any ideas and suggestions would be most appreciated.

thanks

1.- You can use a wide subnet. For example: 192.168.x.x/16 give you 64K of address. You can play with the subnet.

2.- In DHCP server poor you have an option called: NEXT POOL. When a pool address is empty, it will continue to the next one.

But the option 1 in the correct in this case. A big one pool and nothing else
