Route command to use wildcard

Question

I have a bunch of routes to my LAN line that won't resolve through my WiFi (which is set as 1st order).

sudo route add 10.999.999.999 10.888.888.888

I have a lot more but that's just a sample. This works great but sometimes I need access to another Network asset which means I have to go add it to the list again.

Can I make it so I route any IP address starting with 10 gets rerouted through the LAN router?

Something like this:

sudo route add 10.* 10.888.888.888

THIS DOES NOT WORK

My Setup:

I have two internet connections.

1. WiFi - no firewalls - no access to network assets
2. LAN - firewalls - access to network assets

I set WiFi first in my order of precedence and I force certain domains through the LAN connection using my host file to resolve the IP addresses and a routes table to direct those IPs through my LAN router.

Basically I want my cake and eat it too.

Here is what I ended up with:

#! /bin/bash    
sudo route -n flush
sudo route add -net 10 10.255.255.255    
networksetup -setairportpower en0 off    
sleep 2    
networksetup -setairportpower en0 on

This flushes the route table, routes any traffic starting with the ip address 10. to my LAN connection's router, then restarts the wifi router (en0).

Answer 1

The correct form to add a net route is

route add -net 10 $GW

Obviously you have to replace $GW with the ip address of your gateway.

Answer 2

You can use for loops. Here's an example:

for i in {0..255}; do
    for j in {0..255}; do
        for k in {0..255}; do
            sudo route add 10.$i.$j.$k 10.888.888.888
        done;
    done;
done
