# Routing

By default the Gateway setting in the network configuration adds in default routes for all interfaces.

### Step 1) Edit network config file

The system can add additional routing by editing the file

```plaintext
/opt/fmadio/etc/network.lua
```

### Step 2) Locate the route section

In the section named

NOTE: if the section does not exists, it can be added

```plaintext
["route"] =
{
},
```

### Step 3) Add routes

Additional routing can be added by setting additional routes. For example adding a route for 192.168.100.0/24 to go via gateway 192.168.50.1. Looks like the below configuration

```plaintext
["route"] =
{
       "-net 192.168.100.0/24 gw 192.168.50.1",
},
```

Multiple routes can be added as shown below

```plaintext
["route"] =
{
    "-net 192.168.100.0/24 gw 192.168.50.1",
    "-net 192.168.200.0/24 gw 192.168.50.1",
},
```

### Step 4) Validate config file

Once editing has finished, run a syntax check to confirm the config file is good

```plaintext
fmadiolua /opt/fmadio/etc/network.lua
```

The expected output is shown below

```plaintext
fmadio@fmadio200v4-636:~$ fmadiolua /opt/fmadio/etc/network.lua
fmad fmadlua Nov 12 2025 (fmadiolua /opt/fmadio/etc/network.lua )
done 0.000062Sec 0.000001Min
fmadio@fmadio200v4-636:~$
```

### Step 5) Reboot

After the setting is made, a system reboot is required for it to take effect.
