OVPN review
If I needed to reach a service on a home computer while it was connected to a VPN, I’d check whether the plan supports incoming connections. OVPN’s standard plan lets you forward selected ports, so there’s a way to reach that service through the VPN.
Check the port your service needs
OVPN’s help guide lists up to seven forwarded ports per account on the standard plan. The available range starts at 49,152. You can choose TCP, UDP or both, then reconnect the VPN for the change to take effect. If you need to keep an existing port below that range, OVPN lists its paid Public IPv4 add-on as the option. Check which port your service uses before deciding between the two.
Decide whether you need a fixed address
The standard service uses a shared public address. The Public IPv4 add-on gives you a dedicated address that stays the same across reconnects. That can be useful if someone needs to reach the same address again. Mullvad VPN took a different path and removed port forwarding altogether. I’d keep OVPN on the shortlist if inbound access is the reason I’m looking in the first place.
Anabel’s take
I’d write down the port number first. If it fits the standard range and the address can change, the basic plan covers the feature I came for. A fixed address is a separate reason to consider paying for the add-on.
