This guide covers configuring Windscribe's OpenVPN client on a router running DD-WRT firmware. Every device that uses that router for internet access will route traffic through the VPN tunnel while the OpenVPN tunnel is connected, assuming no policy-based routing bypasses are in place and IPv6 is correctly handled.
Note on app features: A manual router configuration does not include all features available in Windscribe's official apps. App-level firewall controls, automatic protocol failover, and app-managed leak protection are not available in this setup. Leak prevention must be handled manually, as covered in Part 4.
Estimated time: 15–30 minutes.
Use a wired connection to your router while configuring. Changing VPN settings can temporarily interrupt Wi-Fi.
Firmware note: Always use the DD-WRT build compiled specifically for your exact router model. Installing an incorrect build can render a router unresponsive. Before starting, confirm you know how to perform a factory reset on your device in case connectivity is lost during configuration.
OpenVPN is a mature, open-source VPN protocol that encrypts traffic between a client device and a VPN server using TLS. Windscribe supports manual OpenVPN profiles on paid plans through the OpenVPN Config Generator. The current generator downloads one .ovpn profile and retrieves OpenVPN credentials separately. A manual DD-WRT setup requires mapping that profile into the router's admin panel.
Windscribe-Location.ovpn.
Open the downloaded .ovpn file in a plain-text editor. You will use its values and embedded blocks in DD-WRT:
remote line provides the server hostname and port: remote [hostname] [port].
proto line provides the tunnel protocol.dev, cipher or data-ciphers, auth, compression, certificate-verification, MTU, and MSS directives that are present. Match your DD-WRT fields to this generated profile instead of using sample values from another guide.<ca> block. You will copy the certificate contents between <ca> and </ca> into the DD-WRT CA Cert field.
<tls-auth> block. You will copy its contents into TLS Auth Key and preserve the profile's key direction when your DD-WRT build exposes that setting.
Windscribe generates a separate set of OpenVPN credentials distinct from your main account login.
Figure 1: The current OpenVPN generator produces one profile, with credentials retrieved separately. The diagram shows which profile values and blocks DD-WRT needs.
Before enabling: Go to Administration > Backup and save a copy of your current DD-WRT configuration. If the VPN setup breaks connectivity, you can restore this backup after resetting or regaining access to the router.
Set Start OpenVPN Client to Enable. Additional configuration fields will appear below.
Use the values copied from your .ovpn file in Part 1, Step 3 and your OpenVPN credentials from Part 1, Step 4.
DD-WRT field names vary by build. Match conditional fields to your generated profile and exact router build. If a field is absent, do not invent an equivalent or copy a sample value from another profile.
dev directive. Current Windscribe router profiles use a routed TUN device.
cipher, data-ciphers, and any fallback directive present in your profile. Do not assume one algorithm applies to every OpenVPN version.
auth directive.
Older builds: If your DD-WRT build does not show Username and Password fields after enabling User Pass Authentication, use a DD-WRT build for your exact model/revision that includes OpenVPN username/password fields. Leaving authentication fields blank will prevent the connection from authenticating.
Set Advanced Options to Enable. This reveals the full set of configuration fields.
tls-cipher or tls-ciphersuites directive in your profile. Otherwise keep your DD-WRT build's default.
compress or comp-lzo only when it appears in the generated profile. Otherwise keep compression disabled.
tun-mtu when the profile specifies it. Otherwise keep the build default and change it only for a tested path-MTU problem.
fragment only when present; otherwise leave blank.
mssfix when present. Change it only for a tested MTU or fragmentation problem.
remote-cert-tls, verify-x509-name, or a legacy ns-cert-type requirement using the corresponding control or Additional Config field available in your build.
Use Additional Config only for directives from your generated .ovpn that do not have a matching DD-WRT field:
reneg-sec 432000; the current Windscribe generator intentionally removes that directive from downloaded profiles.
Do not paste complete sample blocks from screenshots or older guides. If you cannot map a directive safely, leave the field unchanged and verify it against your generated profile and exact DD-WRT build.
.ovpn file, find the <ca> block.
<ca> and </ca>, including the complete -----BEGIN CERTIFICATE----- and -----END CERTIFICATE----- lines.
.ovpn file, find the <tls-auth> block.
<tls-auth> and </tls-auth>, including the actual header and footer lines from your file.
key-direction or the direction value from the <tls-auth> tag when your DD-WRT build exposes that control.
Leave Public Client Cert and Private Client Key empty unless your generated .ovpn contains <cert> or <key> blocks. Current username/password Windscribe profiles do not require per-client certificate fields.

Click Save at the bottom of the page, then click Apply Settings. The router usually takes about 30–60 seconds to apply the changes and attempt to connect.
Manual VPN configurations do not automatically block all leak vectors. Complete both steps below before relying on this setup for privacy.
No kill switch: This guide does not add a router-level kill switch. Without separately tested fail-closed firewall and routing rules, a typical default-route DD-WRT setup can return traffic to the regular WAN when the OpenVPN tunnel drops. DNS settings alone do not prevent that fallback.
Figure 3: The tunnel-drop failure mode for this setup. Without separately tested fail-closed rules, traffic can return to the normal WAN and expose the ISP-facing IP.
If unexpected resolvers appear, do not rely on the setup until the DNS path is corrected and retested.
The current OpenVPN generator says some consumer routers do not accept server-pushed DNS. If that applies to your DD-WRT build, configure Windscribe DNS manually as follows. This reduces DNS leakage; it is not a traffic kill switch:
10.255.255.1. This is an internal Windscribe address and works only while connected to Windscribe.
Treat this OpenVPN router setup as IPv4-only unless you have explicitly verified that your generated profile and DD-WRT build route IPv6 through the tunnel. Windscribe's automatic IPv6 handling in the official apps does not configure DD-WRT for you.
fe80::/10 is not internet-routable.
If you require IPv6, do not rely on this setup until you have verified the generated IPv6 route, DNS path, and tunnel-drop behavior on your exact DD-WRT build.
Figure 4: Four independent checks for tunnel status, public IP, DNS, and IPv6. Passing one does not prove the others are safe.
If the connection and leak checks pass, deliberately stop the tunnel and confirm the expected fail-closed or WAN-fallback behavior before relying on the setup.
.ovpn profile for the target location.
remote, proto, cipher/auth, certificate-verification, <ca>, and <tls-auth> values.
<ca> and <tls-auth> blocks were copied without missing lines. Preserve the TLS key direction.
10.255.255.1. Do not treat this DNS setting as a kill switch.
If your DD-WRT build supports WireGuard, it can perform better on lower-power routers than OpenVPN. Look for Setup > Tunnels. If it is absent, your build does not include WireGuard. For setup instructions, use Windscribe's recommended DD-WRT WireGuard guide.
Yes. Manual router profiles require a Pro or Build-A-Plan subscription. Build-A-Plan can generate profiles only for locations included in the plan; the Free plan does not include the OpenVPN config generator.
It covers devices that use this router as their internet gateway while the OpenVPN tunnel is active, unless another router, VPN app, guest network, VLAN, or policy-based routing rule sends them elsewhere. Without tested fail-closed rules, traffic can return to the regular WAN if the tunnel drops.
No. The official apps include the Windscribe Firewall, automatic protocol failover, and automatic IPv6 handling. A manual router profile does not configure those app features. R.O.B.E.R.T. filtering depends on the account and the router actually using Windscribe DNS; verify the DNS path instead of assuming it.
Without separately tested fail-closed firewall and routing rules, a typical default-route DD-WRT setup can return traffic to the regular WAN. Application traffic may still use HTTPS or other encryption, but it is no longer protected by the VPN tunnel and the ISP-facing IP can be exposed.
Treat it as IPv4-only unless the generated profile and your exact DD-WRT build explicitly route IPv6 through the tunnel and pass IPv6, DNS, and tunnel-drop tests. Otherwise disable IPv6 as described in Part 4, Step 2.
Yes. In the OpenVPN Config Generator, select your Static IP under Location / IP. If prompted, select the correct Static IP device before retrieving credentials.
On routers with older or lower-power CPUs, yes. OpenVPN encryption is CPU-intensive. If your DD-WRT build supports WireGuard, that protocol is significantly lighter on hardware.
Yes, but generate a fresh .ovpn profile and compare every relevant value and embedded block. Do not assume that changing only the hostname, port, and protocol is sufficient.
Manual router profiles require a Pro or Build-A-Plan subscription. Build-A-Plan can generate profiles only for locations included in the plan.
