Here, we will set up an environment to allow a PC get DHCP IP address in specific IP 

pool according to its DSL port, VLAN ID and the option 82 string. In this case, the 

PC is behind 25

th

 DSL port and the option 82 string is a string “1248”. We use the IP 

Commander as DHCP server. Its IP is 192.168.1.99 and the IP pool is between 

192.168.1.201 and 192.168.1.203 for VID=1, DSL port=25 and the option 82 string is 

“1248”.  

 

Click Advanced Application, DHCP Relay in the navigation panel to display 

configuration screen as shown. You will see the DHCP Relay setup page. 

Enable the 

DHCP relay and Option 82 function. Fill the IP address of DHCP server in this page. 

The IP address is 192.168.1.99 in our case. Also, enter “1248” as the Option 82 string.
