VPN

Hello !

I try to connect m0n0wall pptpd from ubuntu ,but it's really difficulty from me.

From windows XP the vpn working with no problem, but i hasn't got just vista and ubuntu.

My working configs:

from: http://www.cyberciti.biz/tips/howto-configure-ubuntu-fedora-linux-pptp-client.html


$ sudo apt-get install pptp-linux network-manager-pptp

   1. PPTP server name: pptp.vpn.nixcraft.com
   2. VPN User Name : vivek
   3. VPN Password: VpnPassword
   4. Connection name: delhi-idc-01

Open /etc/ppp/chap-secrets file:
# vi /etc/ppp/chap-secrets
OR
$ sudo vi /etc/ppp/chap-secrets
Append line as follows:
vivek PPTP VpnPassword *

Save and close the file.

Create a connection file called /etc/ppp/peers/delhi-idc-01 (replace delhi-idc-01 with your connection name such as office or vpn):
# vi /etc/ppp/peers/delhi-idc-01
Append configuration data as follows:


pty "pptp pptp.vpn.nixcraft.com --nolaunchpppd"
name vivek
remotename PPTP
require-mppe-128
file /etc/ppp/options.pptp
ipparam delhi-idc-01

Close and save the file. Where,

Route traffic via ppp0

To route traffic via PPP0 interface add following route command to /etc/ppp/ip-up.d/route-traffic
# vi /etc/ppp/ip-up.d/route-traffic
Append following sample code (modify NET an IFACE as per your requirments):



#!/bin/bash
NET="10.0.0.0/8" # set me
IFACE="ppp0" # set me
#IFACE=$1
route add -net ${NET} dev ${IFACE}



Save and close the file:


# chmod +x /etc/ppp/ip-up.d/route-traffic

Task: connect to PPTP server

Now you need to dial out to your office VPN server. This is the most common use of pppd. This can be done with a command such as:



# pppd call delhi-idc-01


Result:

ifconfig

Thanks for sharing!  I looked at this briefly before in helping someone with it, looked like a real pain. This should make it easier for those who want to do this in the future.
