Network Routing
DSM provides several network routing options for various network configuration requirements.
To separate network interfaces' network flow in the same LAN:
- Go to Control Panel > Network > General.
- In the General section, click Advanced Settings.
- In the pop-up window, check Reply to ARP requests if the target IP address is a local address configured on the incoming interface.
- Click Apply to save your settings.
This establishes the default routing rule for each network interface, which will cause network packets from each interface be sent out from their own respective physical network interface.
Furthermore, if you have more than two network interfaces in the same LAN, enabling this option causes network flow on each interface to be transported separately. You can then apply separate firewall rules for each interface.
To route each network interface through their respective gateways:
- Go to Control Panel > Network > General.
- In the General section, click Advanced Settings.
- In the pop-up window, check Enable Multiple Gateway.
- Click Apply to save your settings.
This will lead to routing for each network interface in your network to go through their respective gateways.
To change the default gateway:
- Go to Control Panel > Network > Network Interface.
- Click Manage > Service Order.
- Rearrange the gateways by dragging the gateways.
- Click OK.
The gateway at the top of the order will serve as the default gateway for your LAN.
To set up static routing:
- Go to Control Panel > Network > Static Route.
- Click Create.
- In Destination Network, enter the IP address of your destination.
- In Netmask, enter the netmask of your destination.
- In Gateway, enter your destination's gateway address.
- In Interface, select your destination's interface.
- Click OK.
To view the IP routing table:
- Go to Control Panel > Network > Static Route.
- Click IP Routing Table.
- Select a network interface to view its IP routing table from the upper-left drop-down list.
