Setup OpenVPN in Ubuntu

To get my work on time schedule, I must bring it as my homework. It is software development. For this purpose, I have to connect my office computer to home computer with VPN.
1st - ISP's Modem
Open firewall or port triggering: 1194 UDP
ThenVirtual Server, forward incoming connection 1194 port to my office computer's IP address.
2dn - Install OpenVPN
Office / Server: Ubuntu 8.04 (Hardy Heron) Server
Home / Client: Ubuntu 8.04 Desktop
Install openvpn in both computers:

sudo apt-get install openvpn

3rd - Configure the server: (see HOWTO for more)

cd /etc/openvpncp -r /usr/share/doc/openvpn/examples/easy-rsa/2.0/ ./easy-rsa/cd easy-rsa

(optionals)

nano ./vars

Change the values:

export KEY_COUNTRY=ID
export KEY_PROVINCE=KEPRIexport KEY_CITY=BATAMexport KEY_ORG="OpenVPN-TEST"
export KEY_EMAIL="eshabe@gimail.com"

(then):

source ./vars

./clean-all

./build-ca

Pay attention in “Common Name”. Example answer: "myfirstvpn"

./build-key-server server

Pay attention in...
“Common Name” - my answer is “server”
“Sign the certificate? [y/n]” - answer “y”
“1 out of 1 certificate requests certified, commit? [y/n]” - answer “y”

./build-key client1

./build-key client2

./build-key client3

./build-dh

Copy key files:

cd /etc/openvpn

cp easy-rsa/keys/server.crt .

cp easy-rsa/keys/server.key .

cp easy-rsa/keys/ca.crt .

cp easy-rsa/keys/dh1024.pem .

Copy example config file:

gunzip /usr/share/doc/openvpn/examples/sample-config-files/server.conf.gz

4th - Configure the client
Copy key files:

cd /etc/openvpn

scp eshabe@125.x.x.x:/etc/openvpn/easy-rsa/keys/client1.crt client.crt

scp eshabe@125.x.x.x:/etc/openvpn/easy-rsa/keys/client1.key client.key

scp eshabe@125.x.x.x:/etc/openvpn/easy-rsa/keys/ca.crt ca.crt

Copy example config file:

cp /usr/share/doc/openvpn/examples/sample-config-files/client.conf .

Edit config file:

nano client.conf

Change remote value:

remote 125.1.2.3 1194

5th - Try and activate
Try:
(server)

openvpn server.conf

(client)

openvpn client.conf

Yes!! openvpn is ready….

/etc/init.d/openvpn start
