How to establish the connection via Plesk VPN Extension?

Answer

1. Follow Extensions > My Extensions > Virtual Private Networking > Go to Extension and press Switch On .
2. Install Open VPN on the client server.
3. Download Client Package in Plesk and extract it on the client server.
4. If you didn't specify the Remote address in Plesk VPN Preferences, make sure that openvpn.conf in Client Package contains next strings, where 10.123.123.123 is IP-Address or the hostname of the server with Plesk installed:
   

   remote 10.123.123.123
   lport 1194
   rport 1194
   ifconfig 172.16.0.2 255.255.255.252
   daemon
   secret vpn-key
   mtu-disc yes
   comp-lzo
   dev tap
   float
   keepalive 10 60
   ping-timer-rem
   resolv-retry infinite

5. Execute the following command on the client server to apply Open VPN configuration file:
   

   openvpn --config openvpn-package/openvpn.conf

6. Ping servers to make sure that the connection is established, e.g.:

   Server side:

   # tcpdump -nni tap0 icmp
   tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
   listening on tap0, link-type EN10MB (Ethernet), capture size 65535 bytes
   02:08:21.431465 IP 172.16.0.2 > 172.16.0.1: ICMP echo request, id 24925, seq 48, length 64
   02:08:21.431489 IP 172.16.0.1 > 172.16.0.2: ICMP echo reply, id 24925, seq 48, length 64

   Client side:

   # ping 172.16.0.1
   PING 172.16.0.1 (172.16.0.1) 56(84) bytes of data.
   64 bytes from 172.16.0.1: icmp_seq=1 ttl=64 time=1.54 ms
   64 bytes from 172.16.0.1: icmp_seq=2 ttl=64 time=0.398 ms
