For each portmapping , add a rule allowing it to <IFACE>_IN ruleset.
Note: destination address/port are local addresses, even when client is connecting to WAN IP. Make sure the allow rule is above "DROP LAN" rules.
Can you please clarify this? I am having the same problem: I've set up two VLANs on switch0 and created the various firewall rules to keep them isolated. This seems to be working fine, except for the loopback/hairpin. I would like devices on the guest/IoT networks to be able to hit internal services via the WAN IP (and port forwarding).

}Even if I drop Rule 30 (which prevents access to the 192.168.1.0/24 network) in both ISOLATE_<x>_VLAN_IN rulesets, the loopback isn't working. I tried adding the loopback rules in the OP but that didn't help. Loopback for devices already on the 192.168.1.0/24 network is working fine.
Am I missing something obvious? Thanks!
