Open port 22023

We need to open port 22023 for the loki-launcher to work properly.

Run the following command to open port 22023.

sudo iptables -A INPUT -p tcp --dport 22023 -j ACCEPT & sudo iptables -A OUTPUT -p tcp --dport 22023 -j ACCEPT

Then run the following command to make this port remain open on reboot.

sudo apt-get install iptables-persistent
