Port Forwarding allows the option to run a publicly accessible server on the home network by specifying the mapping of TCP and/or UDP ports to a local device. This enables incoming requests on specific port numbers to reach devices such as Web Servers, Mail Servers, Digital Video Recorders (DVR), and gaming devices. Port forwarding is set up by selecting from predefined commonly forwarded ports or by entering specific port(s). This document describes how to gather the client IP address and set up port forwarding by selecting from predefined commonly forwarded ports and by entering specific port(s) in the SBG6580-2.
After completing the Port Forwarding setup, it is recommended to reserve the IP address for the client device the port forwarding is set up for. Please refer to Article # 16767 SBG6580-2: IP Address Reserve Setup.
- Client device IP Address
- The port number(s) and protocol (TCP and/or UDP) of the service
Port Forwarding Setup
- Launch a Firefox or Safari browser. Enter http://192.168.0.1 into the address box, and press the Enter key.
NOTE: A browser message on Chrome, Edge, Firefox, and Opera, may appear when accessing the Web Manager. The message includes 192.168.01 uses an unsupported protocol and ERR_SSL_VERSION_OR_CIPHER_MISMATCH. The Web Manager uses an earlier version of the TLS protocol and does not match the version allowed by the web browser. Safari browsers on Apple PC and mobile devices are not impacted. The workaround to access the Web Manager with a PC is to use the Firefox browser and set the TLS version to 1. For workaround instructions refer to article # 19435 - 192.168.0.1 uses an unsupported protocol.
- A security or private risk alert may appear on the web browser advising users to proceed with caution when accessing the Web Manager. There is no risk in proceeding to the Web Manager. For instructions to bypass the alert screen, refer to article # 18181 - Alert Message for Web Manager Access.
- On the Login page, enter admin or a customized username in the Username field.
- Enter password or a customized password in the Password field.
NOTE: On later versions of the SBG6580-2, the Wi-Fi Security Key is used as the default admin password printed on the bottom white label. For assistance with Web Manager Access, refer to article # 18752 – SBG6580-2: Web Manager Access.
