Create A new Network with new security zone. Unable to ping other networks.

Created a new security zone (Internal) with a new network address range (172.17.0.0/18) for a new site connected using Cisco SD wan device. MY old internal network is using 172.16.0.0/16. from the new network, I am able to ping all firewall interface IP addresses but not able to ping the server in my DMZ Security zone and my internal network in the internal security zone from that network.

But I am able to ping from Firewall to the next-hop IP i.e. CISCO SD wan and the other end new network.

How is the routing for these subnets configured beyond the firewall?

Do you see drop logs for the traffic and what is the reason?
