LinuxQuestions.org - VPN configuration pptp

I need to set up a VPN to access the Windows computer that I use at work.

I first recompiled my kernel with the mppe patch and ppp stuff as modules.
Then tried to install the mppe module:

Code:

modprobe ppp-compress-18

FATAL: Module ppp_compress_18 not found.

This worries me; however, I was able to install ppp-mppe

Code:

modprobe ppp-mppe

Are ppp-mppe and ppp-compress-18 the same??

Then I installed pptp with apt-get

The instructions from my network admin say to add a route like this:

Code:

route add -host vpn.purdue.edu gw $GATEWAY dev $INET

I am using dialup on ppp0 so I use "ppp0" for $INET
But I don't know how to find my internet gateway, so I just left this part out

Code:

route add -host vpn.purdue.edu dev ppp0

I didn't get any errors, but I'm still not sure if it worked.

Config files are below. Seems like it isn't able to authenticate.
Here is the output when I try to start the tunnel:

Code:
