Dear All,

This is my first time here and I would like an advice/help on this little project I created. I am studying for the CCENT (via a course on udemy.com), and I created this project to practice some commands, but this project I made in Packet Tracer is also something I am doing for fun as well. Right now, I am configuring Router-On-A-Stick for Inter-VLAN routing. I configured my network devices, but when I try to ping from PC6 from VLAN 30 to PC9 in VLAN40, it doesn't ping.

I made sure to check my setting and it looks to be right, but maybe there is something I am missing that I may not be noticing. Could anyone please take a look at my network project? I attach a zipped folder that contains file and some text files for the involved devices.
