Setting up WireGuard

On a client

  1. instll wireguard
sudo apt install wireguard
  1. this is basically the same as the tutorial on website
PrivateKey = <private kay of the client>
Address = 10.0.0.3/24  # This IP should be unique to this client within the VPN network

[Peer]
PublicKey = <pubkey of server>
Endpoint = <server ip>:<server port>  # Raspberry Pi's local network IP and WireGuard port
AllowedIPs =  x.x.x.x/24   # Route only some Traffic through the internal network e.g. 10.0.0.0/24
PersistentKeepalive = 25  # Keeps the connection alive

Then if you want to forward packets across network interfaces in the clinent enable this setting

sudo sysctl -w net.ipv4.ip_forward=1

to make it persistant, uncomment the same line on

/etc/sysctl.conf

and run sudo sysctl -p to load settings from file

-> Apply NAT (Network Address Translation)

This is needed for the client to hide the source of packets when forwarding them to the pc across the ethernet interface to the wireguard interface

sudo iptables -t nat -A POSTROUTING -o enp0s31f6 -j MASQUERADE

for the iptables setting s to persist install iptables-persistent and run sudo netfilter-persistent save

sudo apt-get update
sudo apt-get install iptables-persistent

sudo netfilter-persistent save

to check if the changes have stuck use

sudo iptables -t nat -L POSTROUTING -v

Troubleshooting

The terminal process failed to launch: Path to shell executable "/bin/bash --login c" does not exist.

This may happen even if you correctly set the settings file in the remote container this may be a bug)

  • goto: File > Preferences > Settings
  • Click on Terminal
  • Scroll to Integrated > Default profile: Linux
  • set it to bash (usually default value is None)
  • then again in remote settings you will notice that the integrated profile is now changed to bash

For me at this point the error goes away and If I have set the gbash profile definition as above I change the value from bash to gbash`. However I’m not sure if this makes any effect.

click on Terminal
