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.
