[I know there has been a number of postings to this list about setting up
PPTP but I can't find any messages that explain this one setting well.
Perhaps the detailed answers were sent directly to the originator and not
the list. This said forgive me for opening an old subject again. JS]

Can someone clarify this step from the GNAT Box and PPTP setup instructions
(URL: http://www.gnatbox.com/Pages/Tutor/pptptutor.html):

- Add a static route for the PPTP Virtual network and use the real IP
address of the NT PPTP server as the gateway to the virtual network. 

I've got the inbound tunnel and the remote access filter setup. Also have an
alias for the external address and a static address mapping from the
internal address to it's external address. It seams to be working fine
without any static route. There are odd happenings but I think they are DNS
related (like, when accessing a server by name it's external address is
returned instead of the internal address for use through the tunnel). Is
this static route really needed in the GNATBox configuration and what is it
used for?

In particular what is the "PPTP Virtual network"? My first guess was the
subnet that the PPTP server is located on. In my case this is the protected
network. GBAdmin doesn't like that, giving a 'WARNING Network address for 1,
matches "PRO" network address (www.xxx.yyy.1)'. My next guess was that this
should be the range of IP addresses defined in the PPTP server. This makes
some since but I don't know why the GNATBox would need to talk or route to
any of these addresses (after all they are all part of the protected network
and can be directly addressed). Also this is defined in the server PPTP
settings but the range does not need to be a maskable set of values (ie: our
NT administrator used www.xxx.yyy.191 to www.xxx.yyy.198). (Don't ask me
why.)

Am I completely off here?

Thanks for any enlightenment,
