Creating static routes

Note

The default static route (0.0.0.0/0) is used for VMs with public IPs. If you need to create a NAT instance, create it in a separate subnet.

Management console

CLI

To create a route table and add static routes:

Open the Virtual Private Cloud section in the folder where you want to create a static route.
Select the network to create the route table in.
Click Create route table.
Enter a name for the route table.
- The name must be unique within the folder.
- The name may contain lowercase Latin letters, numbers, and hyphens.
- The first character must be a letter. The last character can't be a hyphen.
- The maximum length of the name is 63 characters.
Click Add route.
In the window that opens, enter the prefix of the destination subnet in CIDR notation.
Specify the next hop, which is an IP address from the allowed ranges.
Click Add.
Click Create route table.

To use static routes, link the route table to a subnet:

In the line with the desired subnet, click .
In the menu that opens, select Link route table.
In the window that opens, select the created table from the list.
Click Add.

$ yc vpc network list
+----------------------+-----------------+
|          ID          |      NAME       |

Create a routing table in one of the networks. Use the following flags:
- name — The name of the route table.
- network-id — The ID of the network where the tables will be created.
- route — The route settings with two parameters:
  - destination — The destination subnet prefix in CIDR notation.
  - next-hop — The internal IP address of the VM from the allowed ranges that traffic is sent through.
```
$ yc vpc route-table create --name=test-route-table --network-id=enp846vf5fus0nt3lu83 --route destination=0.0.0.0/0,next-hop=192.168.1.5

To use static routes, link the route table to a subnet:
