Firewall blocking Port forwards on L3 switch

[Boxx1e]

Hi,
I am facing issues with port forwarding. Specifically, seeing blocks from the Default deny / state violation rule. I have had the exact same configuration options on my PfSense FW and moved to OpnSense to see that it does not work as intended.
I've tried Factory resetting and trying the setup to no avail.

At my wits end here. I don't want to go abck to Pfsense or with another FW vendor, since I quite like the way OPNSense handles things.

My Setup:
Version: OPNsense 25.7.3_7-amd64
[ONT]>[OpnSense]>[L3Switch] (Transit lan 10.10.10.10)>VLANS

Hi Boxx1e,

would you please also show your firewall rules for the WAN interface...

Also, I found this out accidentally, and due to my lack of knowledge; when I turn off syn flood protection, port forwarding works, but the buffers fill up. Which is I think intended?

This whole thing is bizzare
