For some VPN connections, subscribers may need access to a routable public IP 
address, rather than a NATed LAN address.  Configuring VLAN Static IP allows 
subscribers to reserve a public IP from the ISP for a limited time.  You will need one 
or more extra public IP addresses from the ISP to use this feature. Prior to 
authentication, these subscribers are treated like any other subscriber with a proper 
LAN IP address.  After authentication, the subscribers are visible in the controllers 
WAN side with the Static IP Address configured.  They are not NATed by the 
controller.  This feature can be utilized by subscribers using a VPN connection that 
does not support NAT Traversal, or multiple subscribers using the same VPN server 
at the same company.   Subscribers can get the available static IP addresses 
automatically from the Static IP address List page.  The page contains all the 
correct IP properties, and the available addresses are displayed automatically. 
 
Subscribers can also receive the Static IP addresses automatically via DHCP.  
Subscribers who request a static IP address will be redirected to a page with a 
message and configurable timer.  During the timer duration, their computer will 
receive  a  public  static  IP  via  DHCP.    The  length  of  the  static  IP  DHCP  lease  is 
configurable.  The link to the configuration page appears on the Local and Custom 
login pages automatically, or you can put the post form on a portal page using the 
HTML code from Automatic VPN External HTML Page Code.  Subscribers will 
receive an error if all of the available static IP addresses are in use.  After receiving 
the static IP address via DHCP, the subscriber must login normally with 
username/password, terms of service, etc. 
 

Note: When a subscriber clicks on the VPN Static IP link, or the post form is submitted to 
the Controller from a portal page, a Static IP address is reserved for that MAC Address for 
two hours (or as configured) whether the subscriber it logged in or not.  Only one IP is 
assigned per MAC.
