SMC Networks SMCWHSG44-G Virtual Server Mappings, Dhcp Server, To expose preset internal servers

Page 59

A DMZ (DeMilitarized Zone) host receives all unrecognized TCP/IP packets from the NAT server on the Router; therefore TCP/IP networking applica- tions running on the DMZ host would have better compatibility with NAT. To specify the DMZ host:

•Enter the private IP address of the computer to be used as a DMZ host, and select the corresponding check box.

2.4.3.2. Virtual Server Mappings

Fig. 64. Virtual Server Mappings.

The SMCWHSG44-G enables you to expose internal servers on the intranet through NAT to the Internet for public use. The exposed internal servers are called virtual servers because from the perspective of hosts on the Internet, these servers are invisible in terms of TCP/IP.

To expose “preset” internal servers:

1.Input the service name (FTP, IMAP4, SMTP, POP3, TELNET, and HTTP) for the kinds of servers you want to expose.

2.Specify the private IP addresses of the internal servers.

3.Select the protocol type (TCP or UDP) of this service

4.Select the WAN port interface for particular service port.

5.Input the LAN and WAN port range which will be associated to this service. Note that the port range of LAN and WAN must be the same length.

2.4.4. DHCP Server

There are three modes of the DHCP Server to be defined in 'Functionality': Disable, DHCP Server, and DHCP Relay.
