Strict MAC binding not working

GiuseppeR

Hello @Zyxel_Melen

I see your answer, but this option is really essential to manage a lot of critical devices.

Do you plan to add the "IP-MAC Binding" option to Nebula?

It will not solve the problem DHCP table that reserves an IP address for a specific MAC address is IP-MAC Binding.

Test this yourself as standalone

Hi @PeterUK

I read what you posted, about the logic for IPv4.

It seems strange to me that placing the DHCP server on the firewall itself and telling the firewall to reserve a specific IP for a specific MAC address, the firewall is not able to assign that IP address ONLY to that specific MAC address.

Hi @GiuseppeR,

After checking with the product team, we will not implement the IP-MAC binding on Nebula because it is an advanced security feature.
Nebula intends to provide a centralized platform with easy configuration and management. Since this feature might cause issues for network newbies, we didn't implement it.
Instead, we encourage advanced users to use Nebula cloud monitor mode for the advanced features.

Hello @Zyxel_Melen

I understand your POV.

Please tell me, is there a trick to export Nebula config and import it in On-Premise mode to avoid to reconfigure the firewall itself?

Have a nice day
