Problems with UniFi and VLANs

Tearing my hair out here.

Am trying to get a couple of UniFi units working. Had this working fine before with our old switches but we've replaced these with new ones and I can't get it working again.

The UniFis are configured with two networks, a 'standard' one which isn't on a VLAN and a guest one which uses VLAN ID 3.

These come into a couple of ports on the switch. Both of these ports are configured as Untagged for VLAN 1 and Tagged for VLAN 3.

Traffic for the standard network is then routed across our LAN just like any other data and this is working fine.

Traffic for the guest network needs to be routed to a dedicated interface on our firewall. This interface is connected to another port on the switch, this time configured as Untagged for VLAN ID 3 only and not included in VLAN ID 1 at all. We have no connectivity on this network at all.

Where am I going wrong?
