It doesn't seem to work properly anymore.

It works fine when I disable "enable only when connecting" though.

When I enable "enable only when connecting", it only works one time. If I disconnect and connect after that one time, it doesn't work anymore.

It does not show the incoming IdentD-request and doesn't reply to it either, causing the server to say: "no identd response".

This is NOT a port-forwarding/firewall-issue, cause if I disable "enable only when connecting", it works fine everytime.
