DHCP Server giving ip's on the middle of the range

Thu Mar 14, 2019 5:38 pm

Good Afternoon everyone,

So my problem is, i have a mikrotik with a DHCP network 192.168.16.0/20 destributing ip's to the company clients, i know mikrotik gives reverse ip's in some cases but in this case the mikrotik is giving ip's starting on 192.168.20.x.

Mikrotik is also connected to and Cisco Access Point who also has the ip 192.168.20.x and that access point is the one who is destributing throught wireless the ip's to the clients.

Is there any configuration that i need to change in the Mikrotik to start on the ip 192.168.31.x or 192.168.16.x?

Thanks you all for the help!

Create DHCP pools (IP -- Pool) and exclude the range that is used by the CISCO device.
You can link the various pools together with, use "next pool" option.

PS: Maybe not best approach to have two identical subnets on different machines. Might confuse routing
decisions.

If DHCP is set up without static leases, then this indicates that assigned IP addresses don't matter, any random IP address from given subnet is just fine.
So I don't get people whining about a particular order of IP address assignment ...

Also I don't understand why post about DHCP server landed in wireless section of this forum.
