US_1:Īlso this Firewall Alias is used in Outbound NAT: To begin lets define our synthetic internal addresses. ProtonVPN addresses (avoid when using multiple connections): We can use NAT 1:1 and Outbound NAT rules to map each of our Wireguard connections’ gateway and network to a different single address network to avoid all route collisions. ProtonVPN uses NAT on their end too so why don’t we also use NAT on pfSense to address this problem. Therefore the routing table rejects adding route collisions for multiple Wireguard connections all using 10.2.0.2/32 pointing to multiple different interfaces. The machine would not know where to send the packets if the same network were allow to point to multiple different interfaces. But why does it cause issues? The reason is the routing table. But, this causes issues when you try to use multiple Wireguard connections on the same machine. This is all well and good when you are trying to use one Wireguard tunnel on a single machine. ProtonVPN attempts to preserve privacy by using a single IP address 10.2.0.2 when you connect using Wireguard. We will have to tweak things from this guide but this gives you a good starting point. Meanwhile, our optional Kill Switch feature stops your internet connection if the VPN ever disconnects, keeping your data protected.Please read this first as it will get you up to speed on setting up a single ProtonVPN Wireguard connection in pfSense. DNS leak protection and IPv6 leak protection ensure that your data is always routed through our servers and never to a third party, for example. Our apps offer several additional security features to ensure your safety on the internet. Keys are also rotated regularly within each session

Forward secrecy generates new keys for each VPN session, so even if one session is somehow compromised, no others are.

There are no known methods to defeat RSA when used with a 4096-bit key size.

RSA-4096 is a cipher that secures the TLS key exchange used to establish a secure connection between your device and our VPN servers.

It is used by the US government to secure top secret information.

AES-256 is an NIST-approved cipher that protects your actual data.

Our apps use OpenVPN and IKEv2 because they are secure VPN protocols, and we implement them at their strongest encryption settings.įor example, both OpenVPN and IKEv2 use the following security features:
