[pptp-server] one way tunnel on w2k not w98 (this time w/text andfeeling)

[Jerry Vonau]

Hey All:

Just a thought, doesn't win2k have packet filtering?
Maybe it's turned on....
See:
http://www.microsoft.com/TechNet/isa/isadocs/CMT_H_PacketOptions.htm#

Ran in to a situation where I could not ping a win2k box on the internet,
but it was connect to me when I ran a netstat.....
