• WINS Server. (Optional) Specifies the IP address of a local Windows NetBIOS Server if
one is present in your network.
• Lease Time. This specifies the duration for which IP addresses will be leased to clients.
If you will use a Lightweight Directory Access Protocol (LDAP) authentication server for
network-validated domain-based authentication, select Enable LDAP Information to enable
the DHCP server to provide LDAP server information. Enter the following parameters:
• LDAP Server. Specifies the name or the IP address of the device that hosts the LDAP
server.
• Search Base. Specifies the distinguished name (dn) at which to start the search, specified
as a sequence of relative distinguished names (rdn), connected with commas and without
any blank spaces. For most users, the search base is a variation of the domain name. For
example, if your domain is yourcompany.com, your search base dn might be as follows:
dc=yourcompany,dc=com.
• port. Specifies the port number that the LDAP server is using. Leave this field blank for
the default port.
4. In the Advanced Settings section, configure the following settings:
• Enable DNS Proxy. If the DNS proxy is enabled (which is the default setting), the DHCP
server will provide the VPN firewall's LAN IP address as the DNS server for address
name resolution. If this box is unchecked, the DHCP server will provide the ISP's DNS
server IP addresses. The VPN firewall will still service DNS requests sent to its LAN IP
address unless you disable DNS Proxy in the VPN firewall settings (see
on page 4-20).
• Enable ARP Broadcast. If ARP broadcast is enabled (which is the default setting), the
Address Resolution Protocol (ARP) is broadcasted on the LAN so that IP addresses can be
mapped to physical addresses (that is, MAC addresses).
5. Click Apply to save your settings or click Reset to discard any changes and revert to the
previous configuration.
Note: Once you have completed the LAN IP setup, all outbound traffic is allowed
and all inbound traffic is discarded. To change these traffic rules, refer to
