Inter-VLAN routing: cannot ping from VLAN 12 to VLAN 13

Hi everyone,

In Packet Tracer I have 8 Cisco 2960 switches and lots of devices in my topology. 

I have 5 VLANs: 11-15. 

I have a 2620 Cisco router with 5 sub-interfaces: fa0/0.11-15 configured with encapsulation dot1Q and assigned to the VLANs respectively.

All devices in all VLANs can ping each other except from VLAN 12 to VLAN 13.

(Although I can ping from VLAN 12 devices to VLAN 13's subnet address and default gateway - but not the devices!!)

(VLAN 13 devices are printers so they can't ping back - or I don't know how).

How do I troubleshoot this issue please?

Hello,

 

post the zipped Packet Tracer project (.pkt) file.

Georg helped me spot the issue - thank you so much!

Essentially I have an access list on each VLAN.

Without realising, I set VLAN 13 to deny communication with VLAN 12. 

Once the ACL for VLAN 13 is removed, everything works!
