How to enable WireGuard on both IPv4 and IPv6?
To make wireguard able to forward packets from the client thorough the server and out to the network, IP forwarding must be activated on both IPv4 and on IPv6. To activate IP forwarding edit /etc/sysctl.conf and then add these lines to the file.
How does WireGuard work as a VPN Server?
WireGuard is a fast and modern VPN protocol. It is a point-to-point VPN, which means it does not have a client-server architecture, but peers, and does not rely on a PKI, unlike OpenVPN. It is super simple to setup to connect multiple machines together.
What are the allowedips for IPv4 and IPv6?
AllowedIPs is the IP addresses that the server is allowed to talk to on that peer. It is recommended using a /32 for IPv4 and a /128 for IPv6. The client config is almost identical to the server config, and there are just some adjustments to make it behave more like a client then a server.
Is the exit node in WireGuard a client or a server?
Wireguard is also a peer-to-peer VPN instead of using the server-client architecture like many other VPN solutions are using; this means that every peer in the VPN can be a client or a server. In this blog post, I’m going to refer to the exit node as the server and the other nodes as clients.
Can a VPN connect to a WireGuard subnet?
Connecting both in a private subnet is easy. The trick to make use of the VPN to forward all of the client’s traffic trough the server is to: Make the client’s WireGuard interface its gateway (default route) Enable NAT between the WireGuard interface and public interface on the server
Where can I install WireGuard on my server?
FYI, it is planned for the WireGuard module to be integrated in the Linux kernel itself. WireGuard can run nearly anywhere, all the installation notes are on the website. I’m usually using Debian 9 or Ubuntu 18.04 on my servers. On Debian, you need to install it from the unstable repository and on Ubuntu from a PPA.
