I think i debugged it to this line: https://github.com/nirmata/kube-static-egress-ip/blob/master/pkg/director/director.go#L148 Connected to container, tried to add routes manually, but ip route yields RTNETLINK answers: Network is unreachable. even though i am able to ping the host (same network) and even connect via ssh. I start to think it's some GKE specific thing (i am using GKE for this), probably the node subnet address does not allow setting the other node as gateway for the route.
