VLAN can't get an IP address from DHCP

[efirhino]

I have 2 seperate firewalls running on opnsense with identical hardware. One has no problems assigning additional VLAN's for IOTDevices and Guest Network. The other firewall is connected to internet via PPPOE and vlan 201. When I create a VLAN for the guest network all devices fail to connect reporting failed to get ip address. The 2 firewall VLAN's are configured exactly the same and running the same hardware. The only difference is the PPPOE using VLAN 201 to connect to the internet.
Everything works perfectly on the non PPPOE setup.  Any help would be appreciated

For the first LAN, there is a default "allow any" firewall rule. Depending on how / when you created the VLAN on your machine, that will not have this rule per default, if you have not replicated it.

Thanks for the reply  - Allow Any rule is active for the additional VLANS.  I have created 3 VLANS and they all have the same issue.

What exactly does not work? Do the clients receive IP adresses via DHCP? Do they receive a default gateway? Can you ping the gateway? Where does a tracroute 8.8.8.8 end?
