DHCP Server

Thu Mar 23, 2017 1:04 pm

Dear Friends,

i have 9 Wireless Routers connected to Ether1..

then assigned static ips to all of them 192.168.66.2/3/4/5/6/7/8/9/10

on Winbox, i setup the Pool ranged from 192.168.66.11 - 192.168.66.254

on Ether1 => ARP : Reply-Only
on DHCP Server => checked "Add ARP for Leases"

Yes all of the users will be forced to use DHCP and will get IP starting from 192.168.66.11 to 192.168.66.254
They couldn't assign static ip anymore..

The problem is, i couldn't ping or access any of those 9 wireless routers
Let's say i want to reboot one of them using web browser and type: 192.168.66.5 for example, i couldn't access any of them.
i have to physically reboot them by unplugging the power adaptor..

-or- maybe when a new firmware is available, i need to update each of them.

How to Force users using DHCP (ranged from .11 to .254), prevent them to use Static IP, but at the same time assign static ip to all of my 9 routers (ranged from .2 to .10)
so that i can access each of them via web browser.

Thank you very much..

Hello,
This is totally normal. You should add arp entries for all 9 access points manually on your IP -> Arp table.
Just find out their MAC addresses and add necessary ARP entries.

Hi..thanks for the reply.. :)

So you mean i should keep the Ether1 => ARP : Reply-Only & check the "Add ARP for Leases" in DHCP Server?

Is there a way to find all of those MAC Addresses without physically looking at them one by one?
Some of them were installed already at the top of the hall, about 20 to 30 meters from ground..i need a hydrolic ladder to reach them..

Thank you very much :)

Temporarily enable ARP on interface, ping those devices and you'll get MAC addresses in IP->ARP. And then just use "Make Static" from context menu or button from properties dialog.

Hi again,
You can see them all on IP -> Neighbors window. But Sob's way is easier.

There is also much better way, assuming your access points are all MikroTik, just implement CAPSMAN, this way you don't even need to set IP addresses on your access points and you can manage updates and all wireless configuration from your main router.
