Just rebuilt my Quad from scratch with the newest udoobunto image. Was adding a simple rule to the INPUT chain. I was applying the same rule set that I have operational on a Pi2 and ran into the error mentioned above. Issuing iptables -L results in: Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination As you can see the INPUT chain exists but it throws the error mentioned above. The only other non VM reference I've found indicated the kernel needed to be rebuilt. Has anyone else run into this error and if so, how did you resolve the issue? Thanks and regards, John
