does not accept inbound Allstar connections

Router configured correctly to forward 4569 UDP to Allstar box internal IP

Router is working with Echolink and DSTAR and working Echolink (both ways) through 29451

No port conflicts

This is my second Allstar node; other is on a tower at a remote sight, so this problem is local only

Wonder if this may be one of the cases described here: http://ohnosec.org/drupal/node/66

Befuddled
