Figure 19: DHCP with RADIUS
We assume that you already have installed FreeRADIUS. Just add these lines to specified files:
• users file:
00:0B:6B:31:02:4B Auth-Type := Local, Password == ""
Framed-IP-Address = 192.168.0.55
• clients.conf file
client 172.16.0.1 {
secret = MySecret
shortname = Server
}
Configure Radius Client on RouterOS:
/radius add service=dhcp address=172.16.0.2 secret=MySecret
[admin@DHCP-Server] radius> print detail
Flags: X - disabled
0 service=dhcp called-id="" domain="" address=172.16.0.2 secret="MySecret"
authentication-port=1812 accounting-port=1813 timeout=00:00:00.300
accounting-backup=no realm=""
[admin@DHCP-Server] radius>
Setup DHCP Server:
1. Create an address pool:
/ip pool add name=Radius-Clients ranges=192.168.0.11-192.168.0.100
2. Add a DHCP server:
/ip dhcp-server add address-pool=Radius-Clients use-radius=yes interface=Local \
disabled=no
3. Configure DHCP networks:
/ip dhcp-server network add address=192.168.0.0/24 gateway=192.168.0.1 \
dns-server=159.148.147.194,159.148.60.20
Now the client with MAC address 00:0B:6B:31:02:4B will always receive IP address 192.168.0.55.
