New port for the "pptp-linux" VPN client. It allows a FreeBSD machine

to connect to a remote NT server, making it behave as if it were on
the same LAN.

+Quickstart for the PPTP client.
+
+Set up your /etc/ppp/ppp.conf based on the example in this directory.
+Make these substitutions:
+
+    SERVER	IP address of the PPTP server
+
+    LABEL	PPP label to use (must be the same on the command
+		line and in the ppp.conf file)
+
+    USER	Your account name on the server
+
+    PASSWORD	Your password on the server
+
+    Change the "add" commands in ppp.conf to set up the routing
+    appropriately.
+
+Note: your PPP program must be new enough to support MS-CHAP
+authentication.
+
+You must run the program as root.  Use a command like this:
+
+    pptp SERVER LABEL
+
+Kill it with ^C when you're done.
+
+If you want to access the remote system from other hosts on your LAN,
+be sure to turn on IP forwarding on the PPTP client machine.
+

+A PPTP client for establishing a VPN link with an NT server.

net/pptpclient/pkg-descr

@@ -0,0 +1,17 @@
+This is a port of the "pptp-linux" PPTP client.  It can establish a
+PPP connection with an NT server, tunneled through a PPTP link over
+the Internet.  In effect, it makes the client machine behave as if
+it were on the same LAN as the server.
+
+I have fixed one serious bug in the program, and have patched it to
+use FreeBSD's userland "ppp" package rather than "pppd" which it
+was originally designed to use.  I found that "ppp" supplied more
+versatility and was easier to set up.
+
+There is no manpage for this package, but you will find some
+quickstart instructions and example configuration files in
+"${PREFIX}/share/examples/pptpclient".
