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
/opt/fmadio/etc/network.luaStep 2) Locate the route section
In the section named
NOTE: if the section does not exists, it can be added
["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
["route"] =
{
"-net 192.168.100.0/24 gw 192.168.50.1",
},Multiple routes can be added as shown below
["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
fmadiolua /opt/fmadio/etc/network.luaThe expected output is shown below
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.
