Optionally, you can configure a public DNS record pointing to the exit IP of your Mullvad VPN tunnel.Īnd that’s it for this little guide. Redirect Mullvad port forward to WireGuard Navigate to Firewall → NAT → Port Forward and add the following rule. Secondly, we redirect the traffic to the WireGuard local peer for external clients. ![]() Navigate to Firewall → Rules → WAN_VPN1 and add the following rule. The WireGuard local peer for external clients listens to port 51888įirst, we allow inbound traffic for the Mullvad port on the WireGuard interface of the outer tunnel.The randomly generated Mullvad port number is 61234.The interface of the outer WireGuard tunnel is named WAN_VPN1.In the following, I’ll assume the following. Only a few steps are needed to configure OPNsense. ![]() Read the official port forwarding with Mullvad VPN guide to find out how to configure your ports. Mullvad port forwarding to the rescue! It allows us to forward any traffic through the “outer” tunnel. But what if you don’t want to expose your “real” IP address to the public? Cloudflare proxying comes to mind, but it operates on layer 7, so it doesn’t work with WireGuard. You can then use the DNS hostname in your WireGuard client configurations instead of an explicit IP. You can check Mullvad's Server Status page to determine which server you feel is the best for long-term use, without having to worry about changing anything in the near future. And as soon it changes, it associates the IP address with a public DNS record, e.g., . You copy nf to replace the existing wg0.conf.) EDIT: Even still, it's probably better to just pick a city/server and stick with it indefinitely. You can configure a DDNS client to monitor your dynamic IP address. A typical solution for this issue is to use Dynamic DNS (DDNS). So every time your public IP address changes, you need to update the VPN client configurations. If you have a residential internet subscription it’s likely your ISP provides you with a dynamic IP address. While you set up the inner tunnel, you might have noticed that the external road warrior clients need to know the public IP of your OPNsense host. Make sure to set it up and verify it’s working before you continue. “Inner” WireGuard TunnelĬonfiguring the “inner” tunnel is also covered by the WireGuard Road Warrior Setup guide from the official OPNsense documentation. ![]() I already cover this topic in-depth in my OPNsense baseline guide. I won’t cover the configuration steps of the “outer” tunnel leading from your OPNsense router to a Mullvad VPN server in this post. This time, I’ll give you more of a high-level overview and reference the relevant documentation instead of a detailed step-by-step guide. It’s pretty nifty because you won’t have to expose your public IP address. In this quick guide, I’ll show you how to use Mullvad port forwarding and OPNsense to create a WireGuard VPN “tunnel-inside-a-tunnel” configuration, to be able to connect to your home network from the outside.
