route – show / manipulate the IP routing table
For outside network (routing traffic to the Internet): route add default gw ipaddress
- [-v] [-A family] add [-net|-host] target [netmask Nm] [gw Gw] [metric N] [mss M] [window W] [irtt I] [reject] [mod] [dyn] [reinstate] [[dev] If]
- [-v] [-A family] del [-net|-host] target [gw Gw] [netmask Nm] [metric N] [[dev] If]
- [-V] [–version] [-h] [–help]
Route manipulates the kernel’s IP routing tables. Its primary use is to set up static routes to specific hosts or networks via an interface after it has been configured with the ifconfig program.
When the add or del options are used, route modifies the routing tables. Without these options, route displays the current contents of the routing tables.
