[pptp-server] linux to linux pptp connection

[Jerry Vonau]

Hey All:

Just playing around, Guess what, 
I got the 128-bit mppe to run with vtund in tty mode. 
Actually I forgot to # them out when playing.
It will take all the pppd options as is, including mppe. 
I'm routing LAN to LAN, I didn't have to change the 
ip-up.local at all. Yes I was doing that with pptp before. 
You can still run dial up clients with pptp.
Total time about 30 mins for both machines.  
Anybody have any thoughts?
