Several subnetworks through the tunnel between Palo Alto and Mikrotik

[melnikov]

Site 2 site allows only two networks to be pulled inside the tunnel (one of them behind the mikrotik and the other one behind the palo alto).I’ve tried different settings and it doesn't help.
Has anyone had experience building a tunnel between them based on GRE tunnel over IPsec?
Several subnetworks need to be passed through the tunnel.

is GRE a requirement?

a regular IPSec tunnel will allow as many subnets as you need, adding GRE will create some limitations because of GRE

I have configured s2s between mikrotik and palo alto.
Local networks go between them. I need to add other networks through this tunnel.
On the Palo Alto, I added another network on the tunnel to the proxy id.
In mikrotik, the accept rule from the LAN(Firewall - NAT) to the network behind the tunnel.
But there is no ping.
Only two networks can be specified in the IPSEC settings.
It does not work to create another policy, as the keys begin to break.
Also, there is no separate interface on Mikrotik (like with GRE).
When adding routes, I indicate the local interface.

Hello,

Do either of the firewall logs show where the pings are failing? It could be a policy rule that is preventing the traffic?
