Router not routing between internal and external network in openstack

I put a floating ip in one instance and she can't get out to the internet, I can ping the two interfaces of the router (internal and external) from one instance, but the router does not route to the physical interface.

note: I can connect to the internet by connecting the instance directly to a public network, but not from an internal network.

When I connect the router to two internal networks it routes normally.

I don't know if the problem is with the floating ip or the router.

I'm new to openstack and I'm still learning.

You could start by revealing how this cloud was set up, if it's an all-in-one cloud or not, and what networking options (core plugin, type drivers, mechanism drivers) you used.

Also, does the host where the router resides have connectivity to the router gateway?

Hi, I'm using the default public cloud that openstack gave me (all in one), I installed openstack pike, I didn't do any configuration. The router has connectivity with the instance and with the physical server, it is not doing routing between the two networks. I allocated floating ip normally.

I can connect the instance on the internet only when I connect directly to a public cloud.

There are several different all in one clouds. They all require some configuration. None of them is public. Which one did you use?

Pike is getting old, why not something more recent?

Which public cloud do you connect to?
