Route Management

About Untangle Server's Routing Table
The Untangle Server's Route Management tool consists of two tables:
- Static Routes. Shows the static routes that you manually added.
- Active Routes. Shows the Untangle Server's "live" routing table.
The Active Routes—the routing table—is what is used to determine where the Untangle Server must send packets based on their destination IP address. When you configure the Untangle Server's interfaces, the Untangle Server adds a default list of entries to the Active Routes table, assuming the Linux kernel supports the interfaces. The default list is the default gateway to the Internet, plus one entry for each subnet configured for an interface, signifying that that this subnet can be reached on this interface.
Routing Network Traffic
In some deployments, hosts might not directly connect to the Untangle Server, yet the traffic from one host needs to be directed to another host. Using static routes, you can configure the Untangle Server to direct traffic that is destined for a network to a specific host.
The Untangle Server evaluates rules in the order that they are listed, starting with the first rule in a table. For each new connection, the Untangle Server evaluates the traffic against active rules until a match (if any) is found. When a match is made, traffic is routed as specified by the rule.
To create a static routing rule:
Before You Begin: Ensure that your Router is in Advanced Mode.
- From the Navigation pane, choose Config > Networking.
- In the Advanced drop-down list, select Routes.
- In the Static Routes table, click the add (+) button. A new row appears in the table.
- In the new row, specify the static routing rule:
- Click Save.
Target/Netmask These fields specify the network that will have its traffic routed. Valid values are in IP address/netmask format. Gateway This field specifies the host that receives traffic that is routed from the specified network. Valid values are in IP address format.
