=====Linux=====

----

If you are using a Linux-based OS, extracting files from the router is simple. Just go to the directory on your PC where you want to relocate the files, right click anywhere and choose the '''Open in Terminal''' option. In the Terminal command line use the '''Secure Copy''' ('''scp''') command to copy the files from the router. The full command should look something like this:

−

$ scp [email protected]:/etc/easy-rsa~~/keys~~/static.key ./

+

$ scp [email protected]:/etc/easy-rsa/static.key ./

−

The '''[email protected]:/etc/easy-rsa~~/keys~~/static.key''' specifies the path to where the Static key is located (replace the IP address with your router's LAN IP); the '''./''' denotes that you want to copy the contents to the directory you are in at the moment.

If you are using Windows, you can copy files from the router using '''WinSCP''', an Open source freeware SFTP, SCP and FTP client for Windows OS. Use the same login information with WinSCP as with CLI or SSH. Once you've connected to the router with WinSCP, copying the files should be simple enough: just relocate to directory where you generated the key, select the Static key file and drag it to directory on your PC where you would like to store it.

==Configuring remote office router==

===~~OpenVPN~~===

+

Before you start configuring the remote office router, set a static IP address on the device you are configuring the router with (e.g. 192.168.1.10). You can find instructions on how to do that here:
