packet02-assignment2: VLAN tag stripped but no ping replays
I'm running official solution to packet02-assignment-2, VLAN tags are stripped but I'm not receiving any replays from ping requests.
You should see no VLAN tags on the echo request packets; the echo replies will still have VLAN tags, because the kernel will reply to the ping even though it is targeting a different interface, and the replies will be routed out the interface that actually has the IP address being pinged (i.e., the virtual VLAN interface).
Tutorial clearly states that I should have received something back. Am I missing something? 🤔
