Chapter 5. Initial Configuration
o Gateway FQDN: Fully Qualified Domain Name (FQDN) of the gateway.
o WAN Interface IP: IP address assigned to the WAN interface of the gateway.
The WAN interface is connected to a public subnet.
o WAN Interface Netmask: Network mask for identification of the public subnet
of attachment of the WAN gateway interface.
o WAN Interface Next-hop Router: IP address of the next-hop-router within the
public subnet of attachment of the WAN gateway interface.
o LAN Interface IP: IP address assigned to the LAN interface of the gateway. The
LAN interface is connected to a private subnet of the enterprise.
Note: Your current management system GUI session is interrupted after you set
and save a new value for the LAN interface IP address. To open a new
management system GUI session you must use the new value of the LAN
interface IP address.
o LAN Interface Netmask: Network mask for identification of the private subnet
of attachment of the LAN gateway interface.
o LAN Interface Next-hop Router: IP address of the next-hop-router within the
private subnet of attachment of the LAN gateway interface (the next-hop
router, or default gateway, should not be confused with the OmniAccess 3500
NLG gateway itself).
o LAN Interface Secondary IP: VPN address of the gateway (LAN:1 virtual
interface). The VPN address is used by cards and laptops to communicate with
applications that run on the gateway (and vice versa) through the IPsec tunnel.
It is included in the inner IP header of the packets exchanged by the gateway
with the card and laptop over the IPsec tunnel. This entry must be filled with
one IP address when the gateway is first configured. Later on, any modification
of the VPN IP address of the gateway must be applied to the
<GUARD_PRIVATE_IP> server type of the [Gateway Configure-> Server Table
Information] window, reachable through the [Gateway|Configure Advanced
Settings|Server Table] path.
o LAN Interface Secondary Netmask: Network mask for the private subnet of
attachment of the virtual interface (LAN:1) associated with the VPN address of
the gateway.
o Root Password: Password for the root account on the OmniAccess 3500 NLG
gateway.
Warning: You MUST set a safe value for the root login password the first time
you are presented with this configurable parameter. Failure to set the root
password upon initial configuration of the gateway parameters is a security
violation that exposes the appliance and your entire network to severe
damage. It is critical to secure and remember the new password. If this
password is lost it cannot be recovered.
o Confirm Password: Confirmation replica of the root account password.
o Active Directory Server IP: IP address of the Active Directory server used by
the enterprise for authentication of the laptop users.
