Solution

route — Manually manipulate the routing tables. More information: <https://keith.github.io/xcode-man-pages/route.8.html>.

Add a route to a destination through a gateway:

sudo route add "{{destination_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 "{{destination_ip_address}}/24" "{{gateway_address}}"

Remove all routes:

sudo route flush

Delete a specific route:

sudo route delete "{{destination_ip_address}}/24"

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

sudo route get "{{destination}}"
