ProSafe Gigabit 8 Port VPN Firewall FVS318G Reference Manual • An IP Address from the range you have defined. • Subnet Mask. • Gateway IP Address (the firewall's LAN IP address). • Primary DNS Server (the firewall's LAN IP address). • WINS Server (if you entered a WINS server address in the DHCP Setup menu). • Lease Time (date obtained and duration of lease). DHCP Relay options allow you to make the firewall a dhcp relay agent. 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, or which is not located on the local subnet. If you have no configured DHCP Relay Agent, your clients would only be able to obtain IP addresses from the DHCP server which is on the same subnet. To enable clients to obtain IP addresses from a DHCP server on a remote subnet, you have to configure the DHCP Relay Agent on the subnet that contains the remote clients, so that it can relay DHCP broadcast messages to your DHCP server. When the DNS Proxy option is enabled, the router will act as a proxy for all DNS requests and communicate with the ISP's DNS servers (as configured in the WAN settings page). All DHCP clients will receive the Primary/Secondary DNS IP along with the IP where the DNS Proxy is running, i.e. the box's LAN IP. When disabled, all DHCP clients will receive the DNS IP addresses of the ISP excluding the DNS Proxy IP address. Configuring the LAN Setup Options The LAN Setup menu allows configuration of LAN IP services such as DHCP and allows you to configure a secondary or "multi-home" LAN IP setup in the LAN. The default values are suitable for most users and situations. Note: If you enable the DHCP Relay feature, you will not use the FVS318G as a DHCP server but rather as a DHCP relay agent for a DHCP server somewhere else on your network. 3-2 LAN Configuration 1.1 November, 2009

LAN Configuration
1.1 November, 2009
•
An IP Address from the range you have defined.
•
Subnet Mask.
•
Gateway IP Address (the firewall’s LAN IP address).
•
Primary DNS Server (the firewall’s LAN IP address).
•
WINS Server (if you entered a WINS server address in the DHCP Setup menu).
•
Lease Time (date obtained and duration of lease).
DHCP Relay
options allow you to make the firewall a dhcp relay agent. 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, or
which is not located on the local subnet. If you have no configured DHCP Relay Agent, your
clients would only be able to obtain IP addresses from the DHCP server which is on the same
subnet. To enable clients to obtain IP addresses from a DHCP server on a remote subnet, you have
to configure the DHCP Relay Agent on the subnet that contains the remote clients, so that it can
relay DHCP broadcast messages to your DHCP server.
When the
DNS Proxy
option is enabled, the router will act as a proxy for all DNS requests and
communicate with the ISP’s DNS servers (as configured in the WAN settings page). All DHCP
clients will receive the Primary/Secondary DNS IP along with the IP where the DNS Proxy is
running, i.e. the box's LAN IP. When disabled, all DHCP clients will receive the DNS IP addresses
of the ISP excluding the DNS Proxy IP address.
Configuring the LAN Setup Options
The LAN Setup
menu allows configuration of LAN IP services such as DHCP and allows you to
configure a secondary or “multi-home” LAN IP setup in the LAN. The default values are suitable
for most users and situations.
Note:
If you enable the DHCP Relay feature, you will not use the FVS318G as a DHCP
server but rather as a DHCP relay agent for a DHCP server somewhere else on
your network.
