Title: Block static ip users and allow dhcp users
Post by: michaldejmek on September 13, 2022, 08:57:48 PM
Hello, can OPNsense block static IP addresses and only allow IP addresses that the computer gets from the DHCP server? The DHCP server will be located on the OPNsense system.  I need to ensure that there are no static IP addresses on the network.  The switches we are using are stupid. 

Thank you ...

You cannot prevent a device, with physical access to you network, from being able to assign itself a static IP.  You can restrict access via MAC address but that is labor intensive.
