route

Manually manipulate the routing tables. Necessitates to be root.

• Add a route to a destination through a gateway:

sudo route add {{dest_ip_address}} {{gateway_address}}

• Add a route to a /24 subnet through a gateway:

sudo route add {{subnet_ip_address}}/24 {{gateway_address}}

• Run in test mode (does not do anything, just print):

sudo route -t add {{dest_ip_address}}/24 {{gateway_address}}

• Remove all routes:

sudo route flush

• Delete a specific route:

sudo route delete {{dest_ip_address}}/24

• Lookup and display the route for a destination (hostname or IP address):

sudo route get {{destination}}
