Add Virtual IP to Sensor Interface
==================================

Virtual IP addresses may be configured on each sensor to aid in anomaly
detection. Virtual IP addresses may be automatically assigned from the pool of
unused IP addresses or manually assigned.

Adding Virtual IP Manually
- Administrator can manually specify and add virtual IPs

Adding Virtual IP automatically
- Unused IP are randomly assigned as virtual IPs by the number of Virtual Honeypot IPs configuration.
- If the Administrator change a virtual IP numbers, Genian NAC check the existing virtual IPs and assign additional virtual IPs.

Virtual IP Conflict Prevention
- Adding Virtual IP Manually : If the IP of the new node and the virtual IP are the same, the virtual IP will be automatically changed to unused IP.
- Adding Virtual IP automatically : If the IP of the new node and the virtual IP are the same, the new node will not be registered.

Viewing Virtual IP Addresses
----------------------------

#. Go to **System** in top panel.
#. Go to **System > System** in the left panel.
#. Click desired Network Sensor IP.
#. Click **Sensor > IP Address** tab.

Enable or Disable Automatic Virtual IP Assignment
-------------------------------------------------

#. Go to **System** in top panel.
#. Go to **System > System** in the left panel.
#. Click desired Network Sensor IP.
#. Click **Sensor > Sensor** tab.
#. Click desired interface name of Virtual IP.
#. Under **Virtual Honeypot IPs** , enter the number of Virtual IP Addresses to automatically assign from the unused IP pool. Enter ``0`` to disable.
#. Click Update.

Adding Virtual IP Manually
--------------------------

#. Go to **System** in top panel.
