OpenVPN Connection to Synology NAS on Windows 7

Initially I had some trouble getting this to work, but figured this out and figured I would pass it on.

This guide assumes you are attempting to set up a VPN tunnel to your Synology NAS over WAN using OpenVPN. While a PPTP VPN connection is much easier to set up and doesn’t require third-party software, OpenVPN has been shown to be signifigantly more secure.

For this, I’m using Windows 7 64-bit. While file locations will likely differ on other OSes, the overall configuration is likely smiliar.

Base configuration

Log in to your Synology NAS using the admin account and install the OpenVPN server from within Package Center.

Once installed, start VPN Server and enable OpenVPN under OpenVPN Server > Settings > OpenVPN.

The following pop-up message will appear instructing you to make sure UDP port 1194 is open:

If your NAS is behind a router, make sure you have port forwarding set up to forward UDP port 1194 to your NAS.

If you are using the Synology Router Config tool, you can set the port forwarding from Control Panel > Router Configuration > Create. You’ll find the port setting under Built-In Applications as shown below:

If you’re setting up port forwarding in your router, then the Synology Router Configuration tool isn’t needed. Use one or the other, whichever you prefer.

Install OpenVPN

Download and install the OpenVPN application for your OS from OpenVPN community downloads. Install using the defaults.

Getting the configuration from the Synology OpenVPN server

Before the client software can be configured, a few files (specifically the OpenVPN configuration files and the certificate) need to be downloaded from the Synology NAS. from the NAS, go to OpenVPN Server > OpenVPN and click on Export Configuration. This will download a zip file containing the two needed files plus a third README file. You can either refer to the README for instructions or simply continue reading.

Configure the OpenVPN client software

Open windows explorer and navigate to “C:Program Files (x86)OpenVPNconfig”. Copy the openvpn.opvn and ca.crt files from the openvpn.zip file you downloaded earlier to this directory.

Right-click on openvpn.ovpn and open it with notepad (or your favorite text editor) and make the edits explained below:

Change the line starting with remote to specify your or your server’s IP address or hostname. For example, if your OpenVPN server is at ovpn.example.com, change it as follows:

remote ovpn.example.com 1194

If your host’s IP address frequently changes, uncomment the float option, by changing

#float

to

float

Or, you can specify an IP address, like so:

remote 192.0.2.0 1194

Also, if you want to redirect ALL traffic across the OpenVPN connection (strongly recommended), uncomment the redirect-gateway option by changing

#redirect-gateway

to

redirect-gateway

Connecting to the OpenVPN Server

Right-click the OpenVPN GUI desktop icon and select “Run as administrator”. (You can edit the shortcut to always start with administrative privileges by right-clicking on it, selecting Properties, then Compatibility, then checking Run this program as an administrator.)

The OpenVPN GUI icon will appear in your taskbar, and it will appear red. Right-click on it and select Connect. You will be prompted for your username and password (as used on your Synology NAS) to connect.

If you’re having trouble authenticating make the account you are trying to connect as has access to the VPN server. Look in VPN Server > Privilege to verify account access.

That’s it! You should have a working OpenVPN tunnel connection working after following these steps. If you have any suggestions, comments, or feedback, or just want to share your thoughts, please do it in the comments section below. Thanks!

How to delete all Windows Event logs at once

When troubleshooting Windows it’s often very helpful to start with clean log files. This shows you what’s happening with a system in the moment and you don’t waste time digging through log files and waiting for them to load.

To clear all Windows events from the logs, simply open an administrator-level command prompt and enter:

for /f %x in ('wevtutil el') do wevtutil cl "%x"

After a few moments all of the log files will be cleared.

Batch file use: If you’re using this in a batch file, you need to add an extra % sign to the variable names. Also, make sure you’re running the batch file as an administrator or you will get a lot of access denied messages. %x is valid on the command line only; it needs to be %%x in batch file. Here’s the updated code:

for /f %%x in ('wevtutil el') do wevtutil cl "%%x"

Thanks to stefan for bringing this up in the comments.

Migrating password data from LastPass to 1Password

This explains a fairly simple way to migrate your LastPass data to 1Password using Windows.

First, open your LastPass vault by going to https://lastpass.com and logging in.

Next, under the Actions column on the left, click Export.

For the next part, you’ll have to save the decrypted data to a CSV file. I was using Chrome when I did this, but I’m certain the instructions for any other browser aren’t too much more difficult.

When your decrypted LastPass vault data appears, click the wrench icon and choose ‘Save Page As…

In the file prompt that appears, name the file something you can remember and give it an extension of .CSV. For example, lastpass.csv

NOTE: Your exported CSV contains ALL your LastPass vault data in PLAIN TEXT.

Now, open 1Password and import your LastPass data as follows:

From within 1Password, select File > Import and select the CSV file you just exported from LastPass.

On the Select Columns screen, map the fields as follows:

  • Title -> name
  • username -> username
  • password -> password
  • location -> url
  • description -> extra

Click OK, then click “Yes to all” on the next screen.

After a few moments your password data should be loaded into 1Password.

Note: Your LastPass secure notes will import with ‘sn’ in the location field.
