I am using V0.8.18, WinPcap 2.1,  on a WIN2K Server acting as a VPN router.
Whenever I capture packets on the "external" NIC (connected to the internet
via SDSL) all of the GRE packets show "Encapsulated PPP [Malformed Frame] in
the Info column of the capture display.  VPN is working properly between the
two sites.  I am just curious to know what is "malformed" about the frames
and whether this is an indication that something is, in fact, awry.  Any
input?
