Routing 3750X and Firewall

Hello Dudes !

Nowadays i'm working on my own lab at the office, before installing the equipment. My problem is the routing between the Catalyst 3750x and the Firewall Fortinet connected to my ISP (Service Provider/Internet).

I have briefly set on Catalyst 3750x :

Enable Routing :

     ip routing

Create Vlan:

     vlan 10

     name Data

     interface vlan 10

     ip address 192.168.10.254 255.255.255.0

Switch Port:

     switchport mode access

     switchport access vlan 10

     spanning-tree portfast

The Port (Giga 1/0/24) thats connect to my Fortinet

     no switchport

     ip address 192.168.100.1 255.255.255.0

Then add a default route to Fortinet Interface (Internal) Next Hop:

     ip route 0.0.0.0 0.0.0.0 192.168.100.2

On my Laptop:

     IP 192.168.10.10 / 255.255.255.0

     Gateway 192.168.10.254 (Interface VLAN 10)

     DNS Ex. 8.8.8.8

When I do ping to my Gateway 192.168.10.254 .. it Works !!

When I do ping to Catalyst Interface that connects to Fortinet 192.168.100.1 .. it Works !

But , when I do ping to Fortinet Interface .. Fail !!

The switch catalyst can ping fortinet interface 192.168.100.2 , and fortinet can ping

Catalyst port 192.168.100.1.

I was following this Guide

http://www.cisco.com/en/US/tech/tk389/tk815/technologies_configuration_example09186a008019e74e.shtml

Any ideas ?

Routing 3750X and Firewall

The solution was :

1.- Fortinet to LAN Switch 3750x = Static Route

2.- LAN Switch to Fortinet = Default Route

Thanks.
