I'm just about wrapping up a migration from W2K/Exch2K to W2K3/Exch2K3 and
went to configure RAS/VPN as I'm finishing up and find that I can't do this
on Win2K3 unless I have two network interfaces, or so the wizard tells me. I
also tried to set this up directly in the Routing and Remote Access applet
with the same message. In Win2K, I have it working just fine with a single
NIC. Is there NO way to set up RAS in W2K3 with a single NIC? Thanks for any
pointers. -- tom c
