This is normal for a forwarded port which cannot get replies back to
the originator. Closed means you get an icmp-port-unreachable reply
back. Open means the SYN/ACK connection negotiation succeeds (although
with a stealth scan you do not complete the negotiation.) Filtered
means ... anything else. You don't get anything back.
