Preconfigured 161.26.0.0/16 Routes on Customer Hosts

SoftLayer will be enabling a new route on all newly provisioned servers to support future products.
 

  • The route points any address in the 161.26.0.0/16 range (161.26.0.0 255.255.0.0 | 161.26.0.0 -161.26.255.255) to the backend private network.
  • This IP block is assigned to SoftLayer by IANA and will not be advertised on the public Internet.
  • Only SoftLayer systems will be addressed out of this space.
  • ACLs on customer servers, virtual servers, and Vyatta gateways will need to be updated to allow customer's hosts to use SoftLayer services configured with IP addresses out of this range.

 

How to add the new routing for various OSes

  • Windows 2003 Standard and Enterprise - You will need to add the persistent route from the command line by typing -
    route add 161.26.0.0 mask 255.255.0.0 10.0.0.1 -p

    Note: Replace 10.0.0.1 with your private gateway IP address
     
  • Windows 2008 Server Core - You will need to add the persistent route from the command line by typing -
    route add 161.26.0.0 mask 255.255.0.0 10.0.0.1 -p

    Note: Replace 10.0.0.1 with your private gateway IP address
     
  • Windows 2008 Web, Standard, Enterprise, and Datacenter - You will need to add the persistent route from the command line by typing -
    route add 161.26.0.0 mask 255.255.0.0 10.0.0.1 -p

    Note: Replace 10.0.0.1 with your private gateway IP address
     
  • RedHat, Fedora, and CentOS - You will need to create a new route by editing/creating the following file - /etc/sysconfig/network-scripts/route-eth0
    Once you create that file, you will need to put the following inside it - 161.26.0.0/16 via 10.0.0.1

    Note: Replace 10.0.0.1 with your private gateway IP address

     
  • Ubuntu and Debian - In your /etc/network/interfaces file, you will need to add the following line at the end of the file -
    up route add -net 161.26.0.0/16 gw 10.0.0.1


    Note: Replace 10.0.0.1 with your private gateway IP address
     
  • Vyatta - set protocols static route 161.26.0.0/16 next-hop 172.16.0.26

    Note: Replace 172.16.0.26 with the gateway of the subnet that the machine is on, which should be the same as the gateway defined for the 10.0.0./8 route.

     
  • ESXi - You will need to use the following to add the route to the ESXi host -
    esxcfg-route -a 161.26.0.0/16 10.0.0.1

    Note:  Replace 10.0.0.1 with your private gateway IP address
     
  • CoreOS - You will need to create a static route file in /etc/systemd/network named 10-static.network and it will need to look like this -
    [Route]
    Gateway=10.0.0.1
    Destination=161.26.0.0/16


    Note:  Replace 10.0.0.1 with your private gateway IP address
