TRENDnet BRV204 manual Multi-DMZ, Using a Special Application, Incoming Ports, Outgoing Ports

Internet Features

Incoming Ports

•Type - Select the protocol (TCP or UDP) used when you receive data from the special application or service. (Note: Some applications use different protocols for outgoing and incoming data).

•Start - Enter the beginning of the range of port numbers used by the application server, for data you receive. If the application uses a single port number, enter it in both the "Start" and "Finish" fields.

•Finish - Enter the end of the range of port numbers used by the applica- tion server, for data you receive.

Outgoing Ports

•Type - Select the protocol (TCP or UDP) used when you send data to the remote system or service.

•Start - Enter the beginning of the range of port numbers used by the application server, for data you send to it. If the application uses a sin- gle port number, enter it in both the "Start" and "Finish" fields.

•Finish - Enter the end of the range of port numbers used by the applica- tion server, for data you send to it. If the application uses a single port number, enter it in both the "Start" and "Finish" fields.

Using a Special Application

•Configure the Special Applications screen as required.

•On your PC, use the application normally. Remember that only one (1) PC can use each Special application at any time. Also, when 1 PC is finished using a particular Special Ap- plication, there may need to be a "Time-out" before another PC can use the same Special Application. The "Time-out" period may be up to 3 minutes.

If an application still cannot function correctly, try using the "DMZ" feature.

Multi-DMZ

This feature, if enabled, allows one (1) or more computers on your LAN to be exposed to all users on the Internet. You can set a DMZ PC for each WAN IP address. If you only have 1 WAN IP addresses, only 1 DMZ PC can be used.

This allows unrestricted 2-way communication between the "DMZ PC" and other Internet users or Servers.

•This allows almost any application to be used on the "DMZ PC".

•The "DMZ PC" will receive all "Unknown" connections and data.

•If the DMZ feature is enabled, you must select the PC to be used as the "DMZ PC".

•To use more than one (1) DMZ, your ISP must assign multiple fixed IP addresses to you. You must enter each IP address; you can then assign a DMZ PC for each IP address.

The "DMZ PC" is effectively outside the Firewall, mak- ing it more vulnerable to attacks. For this reason, you should only enable the DMZ feature when required.
