NAT1:1 issues with local IP and Trunk

[askax]

Hello everyone,

I'm new to OpnSense and want to add a network area from a device which I cannot maintain in general.
So I decided to do a 1:1 Nat to mirror a subnet /24 to the other one.

I'm not sure if I'm able to do a 1:1 nat with a Trunk Interface. I've selected the interface which I configured the VLAN

for now, I configured an IP alias: 192.168.179.254/24

And the 1:1 nat with targeting to 192.168.99.1/24

But there is no connection, yet.

Any hints/ideas ?

Thank you in advance
