Hi Aniruddha, Hope you have gone thru the document https://github.com/Juniper/contrail-controller/wiki/Simple-Gateway
Can you check following, 1. Spawn a VM in public VN and see if gateway works for it. 2. The document gives packet flows. Using this, can you identify where packets are being dropped. There is no need to configure SNAT for this feature.

Though currently I am trying to make basic scenarios work but facing problem and need your expert help. Setup is in place with all services up and I am able boot virtual m/c. I have tried following scenarios: 1. Inter-VM communication: * Two VMs, in same virtual network, are able to communicate via private IP [working] 1. Two VMs, in different virtual network, are able to communicate via floating IP. [working] 1. External Network <--> VM communication: * VM is not able to ping external network; ICMP response, is not getting routed to host m/c to routing instance. [NOT working] 1. Steps to reproduce the scenario: * Create a private network and subnet [10.10.10.0/24] on OpenStack Horizon. 1. Create a public network and subnet [172.18.15.30/27] on OpenStack Horizon. 1. Same IPs range [172.18.15.30/27] is configured for vgw in CONTRAIL_VGW_PUBLIC_SUBNET. * Boot a VM on OpenStack Horizon * Create a floating IP from public network on OpenStack Horizon * Associate the floating IP to VM 1. Ping an IP on external network [172.18.15.30/27] 1. Can you please help in resolving this issue? * Do I need to configure the something on Contrail UI, which I have not done as Contrail UI in my setup is not working? * Do I need to enable SNAT as described in https://techwiki.juniper.net/Documentation/Contrail/Contrail_Controller_Feature_Guide/Configuration/70_Source_Network_Address_Translation_%28SNAT%29 1. si there something else that I am missing?
