Find your ExpressVPN account credentials

In order to use ExpressVPN on Synology, you will need to set up a new VPN profile. To set up a VPN profile, you will need a server address, your account credentials, and the IPsec pre-shared key. This section of the tutorial will show you how to find all of this information.

Set up your VPN profile

You may choose to create an L2TP profile or PPTP profile. ExpressVPN recommends using the L2TP setup as L2TP provides much better security than PPTP.

L2TP instructions

On the VPN Connection Method screen, select L2TP/IPSec and click Next.
