Summary

This chapter is an overview of the Routing section in {{{name}}} devices.

Static Routes

Static routes specify over which interface and gateway a certain host or network can be reached. In this page you can configure your own custom routes.

Static IPv4 Routes

---

Below is an example and information about Static IPv4 Routes.

Field	Value	Description
Interface	Default: lan	The zone where the target network resides
Target*	IPv4; Default: 0.0.0.0	The address of the destination network
Netmask*	Default: 255.255.255.255	A Mask that is applied to the Target to determine to what actual IP addresses the routing rule applies
Gateway	IP; Default: 0.0.0.0	Defines where the router should send all the traffic that applies to the rule
Metric	Default: 0	The metric value is used as a sorting measure. If a packet about to be routed fits two rules, the one with the lower metric is applied.
MTU	[64..9000]; Default: 1500	Sets the maximum transmission unit (MTU) size. It is the largest size of a protocol data unit (PDU) that can be transmitted in a single network layer transaction.
Route Type	Default: unicast	Selects route type. Each type specifies a different behavior for the route, available options: unicast local - routes of this type are added to the 'local' routing table and used only for locally hosted IPs. broadcast - routes of this type are added to the 'local' routing table and used by link layer devices that support the broadcast address principle. multicast unreachable prohibit - used to prohibit traffic to specified host or network. When a destination is prohibited, the kernel sends a 'Network is unreachable' response the source address. blackhole - packets that match this type of route are discarded without any response. anycast - -- custom -- -

*Additional notes on Target & Netmask:

You can define a rule that applies to a single IP like this:

• Target: some IP
• Netmask: 255.255.255.255

Furthermore, you can define a rules that apply to a range of IPs. Refer to the table below for examples.

Target	Netmask	Description
192.168.2.0	255.255.255.240	Applies to IPs in the 192.168.2.0 - 192.168.2.15 range.
192.168.2.240	255.255.255.240	Applies to IPs in the 192.168.2.240 - 192.168.2.255 range.
192.168.2.161	255.255.255.0	Applies to IPs in the 192.168.2.0 - 192.168.55.255 range.
192.168.0.0	255.255.0.0	Applies to IPs in the 192.168.0.0 - 192.168.255.255 range.
192.168.2.161	255.255.255.255	Only applies to 192.168.2.161.

Static IPv6 Routes

---

Settings for Static IPv6 routes are the same as for IPv4 only that the target IP and and gateway are different.

Advanced Static Routes

Advanced static routing includes features and concepts that are used in more complex networks.

Routing Tables

---

Below is an example of routing tables. You can create a new one by writing ID (anything you want, but only numbers are allowed), Name and pressing Add button. You can edit them by pressing Edit button

Routing Rules For IPv4

---

Below is an example of routing rules for IPv4. You can create a new rule by pressing Add button, also you can edit them by pressing Edit button.

An example of rule editing window and meanings of all the configurations are presented below.

field name	value	description
Priority	Default: auto-assigned	Controls the order of the IP rules, by default the priority is auto-assigned so that they are processed in the same order.
Incoming interface	Default: Any	Specifies the incoming logical interface name
Outgoing interface	Default: None	Specifies the outgoing logical interface name
Source subnet	IPv4; Default: 0.0.0.0	Specifies the source subnet to match (CIDR notation)
Destination subnet	IPv4; Default: 0.0.0.0	Specifies the destination subnet to match (CIDR notation)
TOS Value to Match	Default: 0	Specifies the TOS value to match in IP headers
Firewall Mark	Default: 0xFF	Specifies the fwmark and optionally its mask to match, e.g. 0xFF to match mark 255 or 0x0/0x1 to match any even mark value
Invert matches	off | on; Default: off	If enabled, the meaning of the match options (Firewall Mark, TOS Value, Source and Destination subnets) is inverted
Matched Traffic Action	Default: Lookup Table	Available options: Lookup table Jump to rule Routing action
Lookup Table	Default: " "	The rule target is a table lookup
