Dynamic Addressing, using DHCP-Relay
IP Address assignment, using FreeRADIUS Server
General Information
Summary
The DHCP (Dynamic Host Configuration Protocol) is needed for easy distribution of IP addresses
in a network. The MikroTik RouterOS implementation includes both - server and client parts and is
compliant with RFC2131.
General usage of DHCP:
• IP assignment in LAN, cable-modem, and wireless systems
• Obtaining IP settings on cable-modem systems
IP addresses can be bound to MAC addresses using static lease feature.
DHCP server can be used with MikroTik RouterOS HotSpot feature to authenticate and account
DHCP clients. See the HotSpot Manual for more information.
Quick Setup Guide
This example will show you how to setup DHCP-Server and DHCP-Client on MikroTik RouterOS.
• Setup of a DHCP-Server.
1. Create an IP address pool
/ip pool add name=dhcp-pool ranges=172.16.0.10-172.16.0.20
2. Add a DHCP network which will concern to the network 172.16.0.0/12 and will
distribute a gateway with IP address 172.16.0.1 to DHCP clients:
/ip dhcp-server network add address=172.16.0.0/12 gateway=172.16.0.1
3. Finally, add a DHCP server:
/ip dhcp-server add interface=wlan1 address-pool=dhcp-pool
• Setup of the DHCP-Client (which will get a lease from the DHCP server, configured above).
1. Add the DHCP client:
/ip dhcp-client add interface=wlan1 use-peer-dns=yes \
add-default-route=yes disabled=no
2. Check whether you have obtained a lease:
[admin@Server] ip dhcp-client> print detail
