Managing subnets in the cloud management portal

Create a subnet

To create a subnet from the Cloud management portal

  • Press Networking and then Networks in the sidebar menu.

  • On the network to which you want to add the subnet, press the Create subnet icon (looking like multiple rows of text with a small + plus sign).

  • Name your subnet.

  • Under Network address you need to input the address in CIDR notation (see the Subnet Format article for more information). For example 192.168.0.0/24.

  • Under Gateway-IP you have the option to either set an IP as gateway or not. If you want a gateway, select Use standard gateway-IP. If you don’t, select don’t use a gateway. The last option enter gateway manually will enable you to choose a specific IP as your gateway. If you are unsure, we recommend Use standard gateway.

  • IPv4 should be selected.

  • If you want to use IPv4, we recommend using DHCP to assign addresses to hosts (as you wont have to login to a host via terminal to set them up). The checkbox should be checked.

  • Under Add pool, add the DHCP scope. That is, the starting and end addresses you want to auto-assign to hosts using DHCP. Press the + (plus) sign above Add pool and enter start and end addresses. For example 192.168.0.10 and 192.168.0.254 if your range is 192.169.0.0/24.

  • Under DNS name servers we recommend adding our servers which are 83.168.225.225 and 83.168.226.226. You can press the + (plus) sign multiple times. You can use any DNS servers you want though.

  • Under Add route, you would add static routes (see: ../router/routing-between-subnets).

  • Press Create subnet

Assign subnet to router

To connect the subnet to a router

  • Press Networking and then Networks in the sidebar menu.

  • Press the network you want to connect to your router.

  • Under Subnet section, check what Gateway-IP is assigned to the subnet you want to connect. Usually, this would be the first IP in the range. If there is not gateway IP, this will need to be set first, using the Edit (small pencil icon) next to the subnets row. Save the Gateway-IP for upcoming steps.

  • Press Networking and then Routers in the sidebar menu.

  • Press the Create interface on the router you want to connect the subnet to. Its a small icon that looks like rows of text with a + (plus) sign.

  • Select the subnet that you want to connect in the Subnet dropdown.

  • Input the Gateway-IP from above step under IP field.

  • Press Create interface
