Question

Hello,

I am using a RUT 240.
I want it to reject DHCP requests (port 67) coming from LAN but accept DHCP requests coming from WiFi.
I cannot do this with web interface because LAN and WiFi are in the same LAN zone.

Is this possible, and how to do this ?

Thank you.
Frederic

Answer 1

Hi,

As another answer suggests, you can create separate network interfaces for WiFi and Ethernet LAN.

• To do that, go to the Network → VLAN → LAN Networks page and add a new network:

• Configure the new network to your liking and go back to Network → VLAN → VLAN Networks tab, set VLAN mode to Port Based, add a new VLAN and assign the new network and the WiFi Access Point to it:

• Click 'Save' and turn off DHCP on your default LAN.

And that should be it. Tell me if this helps or if you need anything else.

Good luck,

DM

Answer 2

Thank you.
How can I do this ?
I only see network instances in VLAN. Should I use VLANs ?
