To skip this setup process, you can purchase a pre-configured router from FlashRouters(новое окно). 

Before starting, you’ll need the following:

• A computer that’s connected to your LAN network so that you can access your DD-WRT router’s web interface(новое окно). To do this, enter the address provided by your router’s manufacturer into your browser’s URL bar. For example, most Linksys and Asus routers use the address 192.168.1.1. 
• Your OpenVPN username and password. These are different from your regular Proton VPN username and password. To find them, sign in to account.protonvpn.com and go to Account → OpenVPN / IKEv2 username.

Note that this guide is for newer versions of DD-WRT. If you’re running an older version of DD-WRT, please update your firmware(новое окно) to the latest version.
