Hello everyone,

I have two instances in two regions that I want to connect on a private network.
I have created the private network on the two regions and also created a different subnet on each region.
GRA3 192.168.0.0/24
UK1 192.168.1.0/24

Could someone help me to connect the two subnets in Horizon or via api so that an instance A on the GRA3 subnet can communicate with an instance B on the UK1 subnet ?

Thanks.

Hello I have the exact same issue.
In addition to the other things that @AbdelS has tested, I have gone a little further and seeing that the web does not allow assigning the same vlan to a network in different regions, I have searched the documentation and ended up trying a couple of openstack guides...
Ending with the private interface of each server configured with the same vlan Id:

* UK1 - ens7.23 -> 10.23.0.1/16
* GRA11 - ens7.23 -> 10.23.2.1/16

One of the things that I have noticed is that all the networks created with the web interface or with openstack by default come out as 'SHARED: FALSE', also if I try to manually create a shared network or a shared subnet I get this error:

`·Error while executing command: ForbiddenException: 403, (rule:create_network and rule:create_network:shared) is disallowed by policy·`

Any help or suggestion will be welcome by both of us...

Thank you very much for your help and your time, regards
