Instance -> private network -> virtual (tenant) router -> external network By using Neutron Gateway the setup is no problem: 1. Create private network 2. Create router 3. Set the external gateway = external network 4. Add router interface to private network 5. Start instance 6. Working For Contrail i found this step by step howto: https://www.juniper.net/techpubs/en_US/contrail3.0/topics/task/configuration/snat-vnc.html It looks similar like the Neutron Gateway todos but it’s not working. If I try the steps in an Contrail based environment Contrail creates a new network like this: „snat-si-left_snat_fe25d509-db30-49f4-90d5-c0347c348f14_e6185d19-c5a7-4534-a200-181bf63744d4“ with an ip range 100.64.0.0/29<http://100.64.0.0/29> The instance can ping the internal router interface. The communication to the external network is broken. In the Contrail WebUI SNAT is enabled for this router. The external network is created with this options: - Shared - External - Reverse path forwarding What is the “snat-si-left_snat…..” network doing? Does anybody has an idea whats the problem with my snat connection/configuration?
