Additional IP addresses

RouterOS Beginner Basics
1

Hi, i just got my first Routerboad and evaluating it. Seems really solid. I’m very new so I apologize if these are stupid questions.

Here is my scenario, (The router is currently set to the default settings)

  1. I need to add ubiquiti radios to the router on 192.168.1.x with static IP’s but I want the DHCP clients (connecting through ubiquiti radios) to us a different subnet (192.168.88.x) I have tried adding a second address (192.168.1.1) and setting my computer to 192.168.1.2 but now i can’t ping 192.168.1.2 nor can I ping 192.168.88.1.

  2. I have also noticed that if i set my computers static ip to 192.168.88.2 and gateway to 192.168.88.1 it pings everything ok but there is no DNS unless I use a DCHP assigned address.

  3. I need to be able to lease more than 254 IP addresses. How can I set this up to allow a DCHP server to assign addresses from 192.168.88.2 to 192.168.90.254?


    Thanks!

/ip address
add address=192.168.88.1/24 interface=lan

/ip dhcp-server networks
add address=192.168.88.0/24 gateway=192.168.88.1 dns-server=192.168.88.1

/ip dns
set primary=8.8.8.8 secondary=208.67.222.222 allow-remote-requests=yes

Now u have additional subnet on LAN side.
just add this address to ubiquiti radio device 192.168.88.XX/24
now make your pc’s dhcp lease static & use this address 192.168.88.XX/24
you will be able to access the router & ubiquiti radio from ur computer while users can’t.

use the default address & dhcp configration for clients.

Thank you!!!

I was close but i forgot to change the DNS settings. It works great now.

Is there anyway I can setup to allow for more than 254 IPs?

AD1)

 If computer address is in the same subnet you should ping any host (if mask on every host is the same.

AD2)

Correct me if I am wrong - you set static IP with DNS server address (as your gateway) and there is no way to resolve domains ? What is your /ip dhcp network configuration and ip dns ?

AD3)

You can resize the dhcp pool in 
/ip pool to 192.168.88.0/22, 
/ip dhcp server network setting

remember to set the same mask in address setting and in dhcp network

Hi,

DNS was my mistake. When I set static IP I was only setting IP and Gateway. I neglected to set static DNS on the client.

Thanks for the tip on the DHCP.
