      Hi,
      I've setup on Netgate 3100 with pfsense 22.01-RELEASE some interfaces as VLAN, all of them are on the mvneta1 physical interface.

      Then I've untagged the ports on a netgear switch to corresponding VLAN.

      It seemed all fine, but looking at logs I find multiple DHCP reuqests from same mac address in a short (too short) time.

      This would happen only on VLANs:

      2023-02-09 19:33:32	23	6      DHCPREQUEST for 192.168.24.34 from mac via mvneta1.24
2023-02-09 19:33:31	23	6	DHCPREQUEST for 192.168.24.34 from mac  via mvneta1.24
2023-02-09 19:33:30	23	6	DHCPREQUEST for 192.168.24.34 from mac  via mvneta1.24
2023-02-09 19:33:29	23	6	DHCPREQUEST for 192.168.24.34 from mac  via mvneta1.24
2023-02-09 19:33:29	23	6	DHCPREQUEST for 192.168.24.34 from mac  via mvneta1.24
2023-02-09 19:33:29	23	6	DHCPREQUEST for 192.168.24.34 from mac  via mvneta1.24

      Any ideas?
      Thanks, BR
