Thanks all for the help, but I am still getting stuck at the error: PPP: tun0: Warning: chat script failed PPTP: log[decaps_hdlc:pptp_gre.c:129]: short read (0): invalid argument
I am using the stock ppp.conf sample file with the below text appended and values changed to match my environment, but upon running the 'ppp -background pptpclient' command, I get the above errors. I'm using the pptp version from the packages and have also tried compiling my own from source (1.7.0) with no success. Although this may be documented well, there doesn't seem to be a clear concise howto or mini-howto for setting it up with all the software together.

The default on OpenBSD seems to be to use pppd, instead of ppp, and the later is the one that supports a MS VPN connection. First, install the pptp package for OpenBSD. Then, in /etc/ppp/ppp.conf, put: pptpclient: set device "!/usr/local/sbin/pptp <ip or host name of your VPN server> --nolaunchpppd" set authname <my username> set authkey <my password> set mtu max 1490 set mru max 1490 set mppe 40 stateless set timeout 60 disable pap disable chap accept chap81 disable ipv6cp disable deflate pred1 deny deflate pred1 set login set ifaddr 10.10.10.100/0 10.10.10.10/0 255.255.255.255 0.0.0.0 For the "authname" parameter, if you need to include a domain, ala "nerdish\mark", use two backslashes instead of one: nerdish\\mark. I found that the MS VPN server I was connecting to didn't require the domain at all, just needed the valid username and password to successfully connect. Then, for a 'manual' connect, do "ppp -background pptpclient", or to have ppp automatically establish the connection whenever traffic tries to use one of the routes you've at your tunnel, do "ppp -auto pptpclient". For me, adding routes via ppp.conf didn't seem to work to swell. Instead, there's a ppp.linkup file that works much better. I believe there's an example file in /etc/ppp/.
