Configuring Global Ranges, Grey Ranges and Templates

  • The following chapters describe the configuration options of the Enterprise Connect S, M, L and XL service.
  • Please refer to separate instructions for the configuration options of the Enterprise Connect XS service.
  • With Enterprise Connect S, the router functions are virtualized.
  • Functions such as DHCP, IP address configurations etc. are provided in the Swisscom cloud and you can configure them via the Enterprise Connect Dashboard.
  • The router on location forwards the VPN traffic and Internet traffic to the virtualized router in the Swisscom Cloud.
  • The virtualized router in the Swisscom cloud is called Cloud Gateway in the Enterprise Connect Dashboard.
  • The router on location is referred to as CPE (Customer Premises Equipment).

Making global standard settings​

These settings are usually configured during the initial network setup and are only selectively changed afterwards.

Global Ranges​

  • The Global Ranges are an administrative aid.
  • Global Ranges help you manage local IP addresses and prevent you from accidentally configuring other IP addresses.
  • You define from which IP ranges addresses are allowed or from which ranges IP addresses are automatically assigned.
  • In the templates and at the locations you can only use IP addresses from a predefined global range, so choose it as generously as possible.
  • Whether you address your locations from the same or different global ranges does not affect connectivity among locations.
  • Allowed values for Global Ranges are the private IP addresses according to the standard RFC 1918, i.e. 192.168.0.0/16.
  • You cannot delete Global Ranges until ip addresses from its scope are no longer configured in a location.
  • To find out where IP ranges are still configured, you can search for IP ranges at the locations.

Configuration​

Under Settings > Global Ranges you can define up to 16 Global Ranges.

  1. Enter a network address from a private IP address area.
  2. Select the size of the Global Range (this is not the size of the nets that you want to assign to the locations later, but the size of the entire range you want to use).
  3. You can give the range a description.
  4. Confirm and save your input with the good sign
  5. Now send the shopping cart so that the change becomes active

Display grey ranges​

  • Grey Ranges are private IP subnets that Are used internally by Swisscom for the LAN-Interconnect (LAN-I) service.
  • If an Enterprise Connect network is connected to a LAN-I network, the corresponding LAN-I Grey Range must not be used for Enterprise Connect locations.
  • Global Ranges cannot overlap with the Grey Range.
  • Grey Ranges are managed by Swisscom and are displayed under Settings > Grey Range.
  • If no LAN-I network is connected to Enterprise Connect, the Grey Range entry is empty.

Templates: configuring location-specific basic settings including DHCP​

  • Under Settings you can predefine various templates for new locations or new groups in one location (VLANs).
  • When activating a location or a new group in a location, you can assign a predefined template to simplify configuration.
  • A maximum of 32 templates can be defined.
  • At locations with the Enterprise Connect LAN service, DHCP Relay cannot currently be configured on the default group corp.
  1. Set the name for the template
  2. If you want to use an existing template for the initial values, select it here
  3. Configure the IP settings.
    • Global Range: When you use the template, the next free IP sub-network will automatically be selected from this range
    • Subnet: Size of the LAN range that is assigned to the location by this template
    • CPE IP Offset: IP address (offset) of the CPE at the location
    • Cloud Gateway Offset: IP address (offset) of the virtual router in the cloud (= default gateway)
    • For EC-M/L/XL the Cloud Gateway IP address is also the CPE IP address
  4. Configure the DHCP settings. You can activate DHCP locally (managed), configure DHCP relay or deactivate DHCP entirely.
    • Managed DHCP settings (local DHCP server on the CPE)
      • DHCP range start: Lowest IP address (offset) from the DHCP range.
      • DHCP range end: Highest IP address (offset) from the DHCP range
      • DHCP DNS suffix: Domain suffix that is assigned
      • Primary DNS server: DNS server as offset from the local IP range (typically the same offset as for the cloud gateway) or as an IP address of a DNS server
      • Secondary DNS server: Alternative DNS server in case the primary one is unavailable
      • DHCP Options: DHCP options 2 to 254 are supported, except options 3, 6, 15, 44, 46, 50, 51, 52, 53, 54, 55, 57, 58, 59, 61, 82, 120, 121, 184.
    • DHCP relay settings
      • DHCP server 1: IP address of the primary DHCP server
      • DHCP server 2: IP address of the alternative DHCP server, if the primary server is unavailable
      • Circuit ID: DHCP option 82: Circuit ID
      • Remote ID: DHCP option 82: Remote ID
      • Proxy mode: Enable/disable the DHCP proxy modes. Proxy mode is disabled by default.
  5. Configure the OSPF settings (only relevant for EC-M/L/XL locations)
