Unable to ping from Local-PC to router's interface

Hi. I am Practicing a simple Lab in which I am using a FortiGate Firewall. The Topology is pasted Below;

I created a policy on firewall to allow ping from local-PC to e0/1 interface of router. I have configured FortiGate interfaces, done static routing on both firewall and on Router. I also created a policy on FortiGate to allow access but still I am unable to ping. What can be the reason??

Hello

Can be a routing issue.

Or can also because e01 and e00 or r3 have the same IP. Try fix it, then if the issue persist share the routing tables of pc, routers and FG.

Can you also share routing table of local-pc and internal router?

INTERNAL is not a router. its a layer-2 switch just used for connectivity. However, routing table of PC is attached.

From PC are you able to ping 10.0.1.254?
From Fortigate are you able to ping 10.200.2.254 and 10.200.1.254?
From R3 are you able to ping 10.200.2.1 and 10.200.1.1?

As suggested by AEK try removing the default route via 19.168.44.1 or add a specific route towards 10.200.2.0/24 and 10.200.1.0.24 subnets via 10.0.1.254 and check.

If the issue is still not fixed, please collect below output from FGT while ping from PC is running to see if the packet reaches FGT or not.

diag sniffer packet any "host 10.0.1.10 and proto 1" 4 10
