Hi
i am an isp and i have about 100 customers, all their address are from 192.168.2.3 to 192.168.2.249.
Part of them have fixed ip stored in their cpe, part of them need dynamic ip via dhcp.
I want to know how to set mikrotik to give dynamic adress via dhcp only from 192.168.2.3 to 192.168.2.80 so i can use other adresses for fixed ip.

Thank you

Just create a pool with that particular IP range. The DHCP server will then in turn only distribute IPs based on that pool.

i did it but it doesn't work, initially dhcp assign proper ip but after some days it assigns ip out of range.

I have to set proper pool only in dhcp server or also in user profile server page or other sections?

Post your config so we can take a look.

What version of RouterOS are you running?

dhcp pool2 is my desired range:

I'm not following this. There appears to be overlapping address ranges. Why don't you just have one subnet for pool1 and another for pool2?

i am using only hs-pool4 for all users ip in hotspot "users profile" and "servers"
and dhcp-pool2 for users in dhcp mode (ip dhcp server).
do not consider other pool.
have i to use dhcp_pool2 only in ip/dhcp server or also in other sections?

thak you for your help.

What I mean is use a contiguous IP pool.

Ok, but tell me: in hotspot "users profile" and "servers" i have to insert a pool with all possible ip of my users or only of users with dhcp?

Sorry but I haven't used hotspot before.

enjoy, let's start afresh - clear your ip pool list.

I assume you've assigned an ip to your hotspot interface (ether2= 192.168.2.2/24).

Now create a dhcp server using setup - ensure the ether2 interface and the 192.168.2.2/24 address space are specified.

Automatically an ip pool will be created using the 192.168.2.2/24 address space. Now go to address pool list and edit that list to contain only the ip range you want available for the hotspot (e.g instead of 192.168.2.1,192.168.2.3-192.168.2.254 you can edit it to 192.168.2.200-192.168.2.254).

Now create a hotspot server using setup - confirm the ether2 interface, confirm the interface address (192.168.2.2) and importantly, confirm the address pool to use for the hotspot (ie the one you edited previously).

That's it - dhcp clients will automatically get ip addresses from the pool and other clients will use the static ip you assign, outside the pool.

Cheers.

thank you very much!
can you explain me the difference between the address pool in "servers" and "user profiles" of hotspot ?

thanks again

The address-pool in hotspot server refers to the pools we have just created and is the primary pool used for one-to-one nat (translates any client ip address to an address within our pool).

As far as i know the address-pool in hotspot user profile is largely redundant for most configurations. But it can be used to perform another layer of nat if a different ip pool (from server address-pool) is specified. I haven't had cause to use it so mine is set to the default - none.

Cheers.
