sudo nano /etc/dhcpcd.conf
add one or multiple snippets to end:
interface eth0
static ip_address=192.168.0.10/24
static routers=192.168.0.1
static domain_name_servers=192.168.0.1
interface wlan0
static ip_address=192.168.0.220/24
static routers=192.168.0.1 #Default gateway
static domain_name_servers=192.168.0.1
Run ifconfig and it should show that ip address under inet
Port forward on the router:
The global IP address can be found on the router
