5. Advanced Settings

Check Use default gateway on remote network
Check Reconnect when the VPN connection is lost.

6. Login to the Synology as admin User (use the same password as when you login to the web interface)

example: ssh [email protected]

Run the following commands
sudo -i [enter Synology password]

cd /usr/syno/etc/synovpnclient/openvpn

ls -al
**Note the number attached to the client_oXXXXXXX file. This number will be unique to your Synology and must be used in the next steps

Get the config file from our servers
wget http://www.frostvpn.com/assets/guides/Synology/frost.cfg
 
Run this command, substituting the number from your client file
sed -i 's/FROST/**number**/g' frost.cfg
 example:
 sed -i 's/FROST/1395413282/g' frost.cfg
Copy the config to client_oXXXXXXXX. This will leave a backup copy of your configuration in case you have to make any changes in the GUI later.
cp frost.cfg client_oXXXXXXXXX
 example:
 cp frost.cfg client_o1395413282
**Additional Notes

Any changes made in the VPN Interface of the GUI will cause these files to be overwritten. Just re-copy the frost.cfg to the client_oXXXXXX file if this happens.

The default configuration file is for Miami, U.S. (gw1.mia4). Change the gateway address by using the following command, substituting the gateway of your choice. We’ll use the Amsterdam gateway in this example (gw1.ams3)
sed -i 's/gw1.mia4/gw1.ams3/g' client_o1395413282
You can check the public IP from the command line of the Synology using
curl ipecho.net/plain ; echo
