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 providing access to the network via VPN, I had to deal with a bunch of mans and faxes on the topic of raising two simultaneously working VPN connections in lines. I raised it in ubunt 9.10 and decided to somehow compile the info into one I hope an understandable fact.

This FAQ will be useful for those who want to configure two simultaneous VPN connections for a local and external network.


First you need to download a package that will provide support for the connection protocol we need, for this we will enter in the terminal:

sudo apt-get install pptp-linux

After the package is installed, go write the connection config to 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 nano terminal editor to the connection configuration file that is created:

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 into the editing 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 access to the Internet of your provider, and login and password for access to the Internet.
Press ctrl + x , then confirm the save with the Y key .
So, the first config is ready, then we write the second one for the local connection:

sudo nano / etc / ppp / peers / connection_name2

Where, again, you can create your own name =)
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 is vpnx.isp.ru- vpn-server for access to the local environment of your provider, and login and password also for local access.
Save the whole thing ctrl + x , then the Y .

Configs are ready.
Now configure autorun and routing to LAN.
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 enter routes for accessing resources directly through an existing connection (without VPN). I commented out an example of such a route, so when adding a route you will have to remove the " ' " symbol from this config.
Where in place 10.66.6.1 should be your local gateway.
Next, let's 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 in the opened editor routes like:

#! / Bin / sh
ip route add 10.200 .0.0 / 16 dev ppp1

Where ppp1 - link to connection connection_name2
Click+ x ctrl , then confirm the settings key the 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.
Write in a terminal:

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

write in the opened editor:

! # / Bin directory / sh
the ip route the add default gw dev eth0

We press ctrl + x , then confirm the settings key the 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 network restart command in the terminal:

sudo /etc/init.d/networking restart

And now the Internet is configured, routes are registered. The ultimate goal is achieved.
I hope I haven’t forgotten anything.
