SwOS • Switch allows DHCPDISCOVER but drops DHCPOFFER

Hey guys!

I'm having a following setup:

(make sure you load all images:)


The problem:
1. When I connect to WiFi_Family (SSID: Uppsala) i get IP assigned beautifully, no problems at all. Full DHCP(DORA) chain
2. When I switch to Mgmt Wifi (SSID: Valhalla) my router receives DHCPDISCOVER and sends back DHCPOFFER but it never gets to my laptop back (Wireshark logs attached in Imgur post)

I'm actually out of ideas. Can anyone help me understand why switch forwards DHCPDISCOVERS over VLAN5 to my OPNsense router but drops DHCPOFFER?
