Hello,
I am creating a small network, with a CISCO2911/K9 router and 3 Cisco 9200L switches, a fortigate firewall with 3 ISPs.
On the router I already have several VLANs created and computers connected, all of them can access the internet without problems, but when trying to ping 8.8.8.8 from my router or from a switch, it is not possible or is unreachable, any idea on how to solve it? .
Some configurations on my router are the following:
interface GigabitEthernet0/0
description LAN
ip address 192.168.9.13 255.255.255.240
ip nat inside
ip virtual-reassembly
duplex auto
speed auto
!
interface GigabitEthernet0/0.10
description Admin_Switch
encapsulation dot1Q 10
ip address 10.10.10.14 255.255.255.240
interface GigabitEthernet0/1
description WAN
ip address 192.168.12.13 255.255.255.240
ip nat outside
ip virtual-reassembly
duplex auto
speed auto
ip route 0.0.0.0 0.0.0.0 192.168.12.14
¡Resuelto! Ir a solución.

Hola
Hay un detalle en la mascara indicada en la interfaz LAN y la mascara asociada a la red que estas permitiendo en la ACL.
interface GigabitEthernet0/0
description LAN
ip address 192.168.9.13 255.255.255.240 = /28
access-list 1 permit 192.168.9.0 0.0.0.255 = /24
Corrige ese detalle.
Lo demas se ve OK.
Saludos

I just did other tests, I added other switches with the IP's: 10.10.10.2, 10.10.10.3 and 10.10.10.4 and from these switches I can ping, but curiously from the router and from my switch with the IP 10.10.10.1 I can't.

I changed the IP of the switch to which the router connects, from 10.10.10.1 to 10.10.10.5 and with that the pin works towards external or public IPs, I don't know what the problem could have been but the ping now works , in the firewall do not change anything.
Thank you all for your support.
