About network interfaces

Access Gateway requires at least one network interface but supports up to ten.

Access Gateway requires eth0, but supports up to eth9

Network interfaces are the mechanism used by Access Gateway virtual application to communicate. By default Access Gateway ships with a single defined interface but can add additional interfaces.  


Interfaces can be used in a variety of ways:

  • To route management traffic - its not unusual to define a specific interface for management connections such as to access Access Gateway Command  Line console or Admin Console.
  • To route application traffic - Using a specific interface for Access Gatewayto protected application traffic as well as another network interface for external traffic.
  • To route monitoring traffic - Using a specific interface to exclusively for Log forwarding, SNMP Monitoring or related traffic.
  • To route special purpose traffic - Using a specific interface for specialized traffic sush as LDAP or Database access.
  • To increase throughput - Network interfaces can be tied together, a process known as NIC bonding, to increase network traffic over a single logical interface.

Defining Network Interfaces

Defining a network interface varies by virtual environment.

  • AWS EC2 uses the concept of an Elastic network interface. Elastic network interface is a logical networking component that is defined and then attached to an instance of Access Gateway at which point it acts as a virtual network card. Elastic interfaces can be attached and detached from instances maintaining their configuration. You must create an Elastic network interface when creating an AWS EC2 based instance of Access Gateway.
  • Microsoft Azure supports the concept of a virtual network interface. Azure network interfaces allow a VM to communicate with the internet, Azure and Azure based services. By default one interface is created for each virtual machine, but additional interfaces may be enabled. enabled. added.
  • Oracle Virtual Box supports up to four network interface adapters. By default only one interface is defined, but by selecting VM settings and choosing the Networks tab, additional interfaces may be enabled. enabled.
  • VMWare Fusion includes a single network interface by default but supports up to ten devices. The performance of the interface is limited only by the host computer. Additional interfaces can be defined using VM settings.
  • VMWare VSphere/ESXi networking features enable communication between virtual machines on the same host, between virtual machines on different hosts, and between other virtual and physical machines. When creating a VM a single network interface is provided, however its possible to add additional network interfaces as required.
