We configure two simultaneous VPN connections in Linux (for access to the Internet and for access to local ISP resources)

Having connected to a new provider, which provides access to the network via VPN, I had to deal with a bunch of man and fak on raising two simultaneous vpn-connections in lines. I picked it up in ubunt 9.10 and decided to somehow compile the info in one hopefully clear fact.

This FAQ will be useful to those who want to set up two simultaneous VPN connections for the local and external networks.


First you need to download a package that will provide support for the connection protocol we need, for this we enter in the terminal:
')
sudo apt-get install pptp-linux

After the package is installed, we go to write the connection configuration in the / etc / ppp / peers folder, for this we need admin rights (if they are not already), for convenience, I will write a standard terminal input with the necessary rights in the terminal editor nano to the connection configuration file :

sudo nano / etc / ppp / peers / connection_name1

Where connection_name1 is the name of the connection being created (you can name it as you like).
Next, enter the connection data in the edit window:

pty "pptp vpn.isp.ru --nolaunchpppd"
user "your login"
password "your password"
unit 0
nodeflate
nobsdcomp
noauth
replacedefaultroute
defaultroute
persist
maxfail 0

Where vpn.isp.ru - vpn-server for Internet access to your provider, and login and password for access to the Internet.
Press ctrl + x , then confirm saving with Y.
So, the first config is ready, then we write the second for a local connection:

sudo nano / etc / ppp / peers / connection_name2

Where, again, the name of the connection can come up with your own =)
There we write:

pty "pptp vpnx.isp.ru --nolaunchpppd"
user "your login"
password "your password"
unit 1
lock
nodeflate
nobsdcomp
noauth
persist
maxfail 0

Where vpnx.isp.ru - vpn-server for access to the local environment of your provider, and login and password for local access.
Save the whole thing ctrl + x , then Y.

Configs ready.
Now we will configure autorun and routing for lokalku.
To do this, edit / etc / network / interfaces :

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp
'up route add-net 10.0.0.0 netmask 255.0.0.0 gw 10.66.6.1

auto connection_name1
iface connection_name1 inet ppp
provider connection_name1

auto connection_name2
iface connection_name2 inet ppp
provider connection_name2

Here you can add routes for accessing resources directly through an existing connection (without VPN). I commented out an example of such a route, so when you add a route you will have to remove the " ' " symbol from this config.
Where in place of 10.66.6.1 should be your local gateway.
Next we go to write route scripts for connection_name2 .
We need to create /etc/ppp/ip-up.d/route
We write in the terminal:

sudo nano /etc/ppp/ip-up.d/route

We write the following routes in the opened editor:

#! / bin / sh
ip route add 10.200.0.0/16 dev ppp1

Where ppp1 is a link to connection_name2
Press ctrl + x , then confirm saving with Y.

Then we make this script executable, for this we write in the terminal:

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

Next you need to create a script to delete routes.
We write in the terminal:

sudo nano /etc/ppp/ip-down.d/route

We write in the editor that opens:

#! / bin / sh
ip route add default gw dev eth0

Press ctrl + x , then confirm saving with Y.

Then we make this script executable, for this we write in the terminal:

sudo chmod + x /etc/ppp/ip-down.d/route

Everything, now we write the command to restart the network in the terminal:

sudo /etc/init.d/networking restart

And now the Internet is configured, the routes are registered. The ultimate goal is achieved.
Hope not forgot anything.
