Summary
Static routes specify over which interface and gateway a certain host or network can be reached. This chapter is an overview of the Static Routes page in {{{name}}} gateways.
The information in this page is updated in accordance with the [[Media:{{{fw_version}}}.bin|{{{fw_version}}}]] firmware version.
Static routes
To find information on static route configuration, refer to the figure and table below:
| Field | Value | Description |
|---|---|---|
| Interface | mobile | lan; default: mobile | The zone where the target network resides |
| Target* | ip4; default: 0.0.0.0 | The address of the destination network |
| Netmask* | 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: none | Defines where the router should send all the traffic that applies to the rule |
| Metric | integer; 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 | integer [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 | unicast | local | broadcast | multicast | unreachable | prohibit | backhole | anycast | -- custom -- ; default: unicast | Selects route type. Each type specifies a different behavior for the route:

*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. |
