Bug fixed

On letmeinfwd daemon shutdown the control port rule was not removed from the firewall. This could lead to letmeind still being reachable, if it was still running. This has been fixed.

In practice this should not be a real problem, though. If letmeind was still running, the communication with letmeinfwd would fail and the user would eventually receive a Nack for the knocking. If letmeind was also shutdown, the port would be closed anyway, regardless of the firewall rule.

An upgrade is recommended.
