• Services - Defines a network service (e.g., web server, FTP and email server)
between the client and server nodes on your network. When you create a
service, you will be allowed to forward public services inward to the internal
(privately addressed) servers on your network. See Services, page 3-53.
• Address Sharing - Address Sharing uses Network Address Translation (NAT)
to allow you to share public IP addresses with privately addressed network
nodes in order for them to access the Internet. See Address Sharing,
page 3-58.
• Internal Servers - Allows an administrator to make a service available from
an IP address, even though the owner of the IP address may not be actually
providing the service. See Internal Servers, page 3-60.
• 1:1 NAT - Allows an administrator to statically map a public IP address to the
private IP address of one of the nodes on your network. This is useful when
trying to preserve a limited number of IP addresses on the WAN network. See
1:1 NAT, page 3-62.
• Firewall - The SPEEDLAN 9200 (via the SPEEDLAN 9200 Configurator)
allows you to control incoming and outgoing traffic. A firewall prevents
unauthorized access to a network. Utilizing the SPEEDLAN 9200 Configurator,
SPEEDLAN 9200 routers can increase security and provide additional support
to users of the network. See Firewall, page 3-63.
• lP Sessions - The SPEEDLAN 9200 firewall offers stateful packet filtering. IP
Sessions allows you to view sessions whose state is currently active. See
IP Sessions, page 3-68.
