This is not an unusual net value within a PKT2+ packet.

In a PKT 2+ format if the origNet is $FFFF it indicates that the origin is a point system and the net is found in the auxNet field. 
Here's a paste from the PKT2+ FSC-0048 documentation:

auxNet field:
    When parsing a Type 2+ packet, if origNet is 65535, the software MUST use
    the value from the auxNet field.  When creating a packet, if the
    originating system is a point, it SHOULD set origNet to 65535 and
    put the net number in this field. 

The reason for this kludge is so that PKT2+ maintains backwards compatibility with PKT2 while also allowing for 4D addressing that was missing in the PKT2 format.

It may be that D'Bridge needs to be updated to support PKT2+ for point support for this to work.
