I bet its because of missing "-f ipv6" flag, so changing the line to include "-f $NFCT_IP_VERSION" like in the other files should make it work. I intend to wait for a few months before adding more test cases to see how stable these tests will be wrt. changes elsewhere in the stack, there are a few other corner cases that would be nice to have coverage for.
