Custom network interface in traefik kubernetes

I am currently installing using helm:

helm repo add traefik https://helm.traefik.io/traefik
helm upgrade traefik traefik/traefik -f values.yaml --install --wait

I was wondering if I could specify which interface to use as I am currently running my k8 cluster on a wireguard interface? When I connect a node behind a CGNAT/firewall traefik is not aware of it.

Thanks
