Running K3S with Traefik on a second entwork interface

Hi,

I am trying to configure the Traefik Ingress Controller to a fixed IP/Interface. I am currently in a 1 Node Setup, where the master node has 2 interfaces. One “normal” IP , lets call it IP1 (for briefity, the node is dualstacked for each IPv4 there is a corresponding IPv6), and one service IP, lets call it IP2.

The traefik ingress controler pod gains as LoadBalancer Ingress values only the IPs from IP1, but not IP2.
I however want the Traefik ingress controller to basically only listen on the Service Ip IP2.

What do i have to configure. I have tried several different configurations like externalIPs, none have worked so far.

Help is much appreciated.
