Add or edit the Firewall Rule for TFTP
THIS INFORMATION IS OBSOLETE
The Linux firewall needs to be updated to allow for the TFTP traffic. To do so, switch to the pixi-admin user, open a terminal window, and enter the following three lines, pressing the return key after each line:
sudo iptables -t nat -I PREROUTING -p udp --dport 69 -j REDIRECT --to-port 8069 sudo bash -c "iptables-save > /etc/iptables.up.rules" sudo bash -c "iptables-save > /etc/iptables/rules.v4"
Type the pixi-admin user's password when requested. If you haven't changed the passwords since the server was installed, your server still uses the default admin password.
