Preparation on the Pi

• Allow connections to the RaspiBolt from your LAN. Check what your LAN IP address is starting with eg. 192.168.0 or 192.168.1 and use the address accordingly. Ending with .0/24 will allow all IP addresses from that network. $ sudo nano /home/bitcoin/.lnd/lnd.conf

  Add the following line to the section [Application Options]: tlsextraip=192.168.0.0/24

• Delete tls.cert (restarting LND will recreate it):
  $ sudo rm /home/bitcoin/.lnd/tls.*

• Restart LND :
  $ sudo systemctl restart lnd

• Copy the new tls.cert to user "admin", as it is needed for lncli:
  $ sudo cp /home/bitcoin/.lnd/tls.cert /home/admin/.lnd

• Unlock wallet
  $ lncli unlock

• Allow the ufw firewall to listen on 10009 from the LAN:
  $ sudo ufw allow from 192.168.0.0/24 to any port 10009 comment 'allow LND grpc from local LAN'

• restart and check the firewall:
  $ sudo ufw enable
$ sudo ufw status

On your Linux desktop terminal:

• Copy the tls.cert to your home directory:
  $ scp admin@your.RaspiBolt.LAN.IP:/home/admin/.lnd/tls.cert ~/

• Copy the admin.macaroon to your home directory:
  $ scp admin@your.RaspiBolt.LAN.IP:/home/bitcoin/.lnd/admin.macaroon ~/

Configure ZAP

• Start the app and select:
  Connect your own node

• Fill in the next screen:
  your.RaspiBolt.LAN.IP:10009
~/tls.cert
~/admin.macaroon

• Confirm the settings on the following screen and you are done!
