LAN PCs not able to connect to Interface IP or internet

[samipk123]

Hello everyone, 

I just started with Fortigate and am trying to learn it by creating a home network, I have done the initial configuration and allowed LAN and DMZ access to outside. Here is a brief of whats going on

[ul]

None of the LAN Client PCS can ping or access the Internet.

None of the clients can access 192.168.99.100(The ip of the Fortigate interface on the LAN side.

All of the PCS can access 192.168.99.101(The Vlan 1 ip of Core Switch).

All of the switches can access Internet as well as 192.168.99.100

All of the PCs can access other PCs on other Vlans.

The Core Switch Has a default route to 192.168.99.100

The Other Switches Have default route to 192.168.99.101(Vlan 1 ip of Core Switch)

All PCs have default routes to their respective VLAN ip on Core Switch.

The DMZ network PCS can access the Internet perfectly without any issue but the LAN network PCs cant.[/ul]

Below is the network and my basic configuration

I Ran a wireshark trace and saw that the packets were getting rejected as they couldnt find the LAN subnets, add a static route back to the LAN ips on fortigate and solved the problem.
