Hello everyone,

as you can see in this thread:

I had an issue when enabling DHCP Server Guard on Nebula platform.

I installed a switch on site and it was unable to get an IP from Sophos firewall, but the switch itself was working properly locally managing traffic between VLANs.

Is there any known issue between DHCP Server Guard and other firewalls' Brands?

It is the first time that I meet this problem.

    Hi @GiuseppeR ,

    Due to the absence of a Sophos router in our testing environment, we attempted to reproduce your case using all steps you mentioned with Zyxel firewalls as DHCP servers but were unable to do so. Additionally, we have not received other reports indicating incompatibility between the DHCP server guard feature and Sophos routers.
