Block dhcp serving on WAN interface?(vyos 1.4)

General questions
1

Have setup dhcp server as example docs but in lab I noticed that dhcp serves on my WAN interface. How can I block/disable this ?

Don’t see any options to set interface for dhcp server.

nmap scan:
67/udp open|filtered dhcps

Edit: maybe it was nothing, can not reproduce again. Was setting up a new proxmox host and it got an ip in the range which was in the range from the lan behind vyos lab. Can’t reproduce if creating new vm’s… strange

You can set listen address (multiple):
