Proton is the clearest fit if you use a supported desktop app and can work with a port that may change after reconnecting. PIA documents in-app port requests on eligible server locations, while TorGuard offers a client-area workflow with TCP or UDP selection. None can be called the best overall on the available feature documentation alone; check your operating system, server location, port persistence needs, and service before subscribing.
Which VPNs allow port forwarding?
Port forwarding lets an incoming connection reach an application or device through a VPN provider’s firewall. It is useful for some peer-to-peer (P2P) clients, multiplayer games, and self-hosted services. It does not guarantee faster downloads or better connections: results depend on the application, peers, network, and server.

The forwarded port must be configured in the application that will receive connections. This is separate from port forwarding on a home router: a router rule opens a path through your local network, while a VPN provider’s rule opens a path through its VPN endpoint.

| Provider | Documented fit and setup | Important limitation |
|---|---|---|
| Proton VPN | Port forwarding is documented for paid plans on Windows, macOS, and Linux. Connect to a P2P server and configure the assigned port in your application. Proton’s port-forwarding guide | The port usually changes after reconnecting, so applications may need updating. macOS support is described as early access. Proton’s port-forwarding guide |
| Private Internet Access (PIA) | Its documentation describes requesting an automatically assigned port in the app. PIA lists P2P, some multiplayer games, and self-hosted services as possible uses. Windows setup; Android setup | Port forwarding is available only on supported VPN server locations and not on US server locations, according to PIA’s Windows guide. The cited setup instructions are platform-specific; do not assume every app or device supports it. |
| TorGuard | Port forwarding is documented for shared and dedicated IPs. Users request and manage ports in the client area and choose TCP or UDP for the service. TorGuard port-forwarding guide; TorGuard knowledge base | Ports below 2048 are not allowed, and some higher ports may be reserved, according to its knowledge base. |
| AirVPN | Worth investigating if you need account-based configuration or multiple forwards; those details are reported by Top10VPN.

- DUAL-BAND WIFI 6 ROUTER: Wi-Fi 6(802.11ax) technology achieves faster speeds, greater capacity and reduced network congestion compared to the previous gen. All WiFi routers require a separate modem. Dual-Band WiFi routers do not support the 6 GHz band.
- AX1800: Enjoy smoother and more stable streaming, gaming, downloading with 1.8 Gbps total bandwidth (up to 1200 Mbps on 5 GHz and up to 574 Mbps on 2.4 GHz). Performance varies by conditions, distance to devices, and obstacles such as walls.
- CONNECT MORE DEVICES: Wi-Fi 6 technology communicates more data to more devices simultaneously using revolutionary OFDMA technology
- EXTENSIVE COVERAGE: Achieve the strong, reliable WiFi coverage with Archer AX1800 as it focuses signal strength to your devices far away using Beamforming technology, 4 high-gain antennas and an advanced front-end module (FEM) chipset
- OUR CYBERSECURITY COMMITMENT: TP-Link is a signatory of the U.S. Cybersecurity and Infrastructure Security Agency’s (CISA) Secure-by-Design pledge. This device is designed, built, and maintained, with advanced security as a core requirement.
How to choose a VPN with port forwarding
Before comparing general VPN features, confirm that port forwarding works for your particular device and connection. Support can vary by operating system, subscription, server, and provider changes.
- Check platform and plan: Proton documents paid-plan support for Windows, macOS, and Linux, with macOS marked early access. PIA’s cited setup guides cover Windows and Android, not every platform.
- Check server eligibility: Proton requires a P2P server. PIA says only supported locations qualify and excludes US server locations in its Windows guide.
- Decide whether a changing port is acceptable: Proton says the active port usually changes on reconnect. If your service depends on a fixed port, confirm current provider behavior before choosing.
- Consider setup and protocol: Proton and PIA document in-app setup for the platforms covered by their guides. TorGuard uses its client area and asks users to select TCP or UDP to match the service.
- Match the feature to your use: Identify the application that needs inbound connections, then check its own instructions for the port and protocol it requires.

Proton VPN
- Use a paid plan and a supported Windows, macOS, or Linux app; note that Proton describes macOS support as early access.
- Connect to a P2P server.
- Enable or locate port forwarding in the app and note the assigned port.
- Enter that port in the application accepting inbound connections. Proton’s BitTorrent guidance includes binding qBittorrent to the correct interface to reduce the risk of IP leaks. Proton port-forwarding instructions; Proton BitTorrent guidance
- After reconnecting, check the active port and update the application if it has changed.
Private Internet Access
- Open PIA’s app on a platform covered by its setup guide and choose a supported VPN server location.
- Enable the app’s port-forwarding request setting; PIA assigns a port automatically.
- Use the assigned port in the application that needs inbound access. The available guide explains the feature for Windows and Android, but the precise controls may differ. PIA Windows instructions; PIA Android instructions
TorGuard
- Sign in to TorGuard’s client area and open its port-forwarding controls.
- Request and manage a port, choosing TCP or UDP to match the application.
- Configure the application to use that port, then confirm the service is listening as intended. Ports below 2048 are unavailable, and some higher ports may be reserved. TorGuard setup guide; TorGuard port limits
What are the security risks of opening a port?
Port forwarding is a connectivity feature, not a privacy upgrade. Any service listening on the forwarded port may receive internet traffic, so a vulnerable or poorly configured service can create a point of exposure. TorGuard advises using strong passwords and two-factor authentication where available, restricting source IP addresses when feasible, keeping exposed services updated, and monitoring access.

Recommended Free Tools
Enable forwarding only for a service that needs inbound connections. Configure the application itself securely and keep its access controls and updates in place.

What the available evidence does—and does not—establish
Provider documentation confirms that these services describe port-forwarding features and explains some eligibility and setup conditions. It does not establish which provider is fastest, safest, most reliable, or best overall, nor does it provide comparable tests of connection quality, privacy, or support. Treat the providers above as feature matches, not a performance ranking, and recheck current terms before choosing because availability can change.
