I’ve got a Problem running Rancher 1.6.10 on Debian 9 with Docker 1.12.6.
When I add Hosts using a unmodified kubernetes environment. The Hosts wont expose UDP Port 500 and 4500 which results that the etcd node wont get healthy.
The Setup is 3 Hosts at the moment. 1 Host Running the Rancher Server and 2 Hosts which should be added. At this time I only can add 1 Hosts because the second one wont connect.
I allready tried to ping the ipsec container on the first host but this wont work. So I really think there is a problem with the overlay network.
I also seems that the ipsec router is stuck:

Has anyone got any idea how to get the Hosts connected?
Let me know if you need more Information
