Does the Slave node do dhcp requests on the internet interface?

Hi,

I've got a UTM9 with active HA. 

I get messages about:

[INFO-107] WebAdmin webserver not running - restarted

WebAdmin webserver not running - restarted

--

HA Status          : HA SLAVE (node id: 2)

System Uptime      : 0 days 0 hours 0 minutes

System Load        : 0.14

System Version     : Sophos UTM 9.411-3

Please refer to the manual for detailed instructions.

I've found out, that the slave node is doing a dhcp request on it's internet device. How can I disable it?

Cheers Marc
