ProSafe Wireless-N 8-Port Gigabit VPN Firewall FVS318N
• WINS server (if you entered a WINS server address in the DHCP Setup screen)
• Lease time (the date obtained and the duration of the lease)
DHCP Relay
DHCP relay options allow you to make the wireless VPN firewall a DHCP relay agent for a
VLAN. The DHCP relay agent makes it possible for DHCP broadcast messages to be sent
over routers that do not support forwarding of these types of messages. The DHCP relay
agent is therefore the routing protocol that enables DHCP clients to obtain IP addresses from
a DHCP server on a remote subnet. If you do not configure a DHCP relay agent for a VLAN,
its clients can obtain IP addresses only from a DHCP server that is on the same subnet. To
enable clients to obtain IP addresses from a DHCP server on a remote subnet, you need to
configure the DHCP relay agent on the subnet that contains the remote clients, so that the
DHCP relay agent can relay DHCP broadcast messages to your DHCP server.
DNS Proxy
When the DNS proxy option is enabled for a VLAN, the wireless VPN firewall acts as a proxy
for all DNS requests and communicates with the ISP's DNS servers (as configured on the
Broadband ISP Settings screens). All DHCP clients receive the primary and secondary DNS
IP addresses along with the IP address where the DNS proxy is located (that is, the wireless
VPN firewall's LAN IP address). When the DNS proxy option is disabled for a VLAN, all
DHCP clients receive the DNS IP addresses of the ISP but without the DNS proxy IP
address.
LDAP Server
A Lightweight Directory Access Protocol (LDAP) server allows a user to query and modify
directory services that run over TCP/IP. For example, clients can query email addresses,
contact information, and other service information using an LDAP server. For each VLAN,
you can specify an LDAP server and a search base that defines the location in the directory
(that is, the directory tree) from which the LDAP search begins.
