Using Remote Management with the

OfficeConnect Cable/DSL Gateway (3C855) and

OfficeConnect Wireless Cable/DSL Gateway

(3CRWE51196)

The OfficeConnect Cable/DSL Gateway and OfficeConnect Wireless

Cable/DSL Gateway can be remotely managed across the Internet. This

would allow a remote user to configure the Gateway while away from the

office. A typical system set-up and the steps needed to remotely manage

the Gateway are described in this document using the OfficeConnect

Cable/DSL Gateway as an example.

1 Configuring the Gateway

To configure the Gateway for remote management, the user must first set-up the

Gateway whilst he has access to it from the LAN. To set-up the Gateway:

1. Browse to the Welcome screen, Password tab.

2. Enable the checkbox “Enable administration from an Internet Host”.

3. Enter one of the following into the “Host IP Address” field:

 If the remote PC obtains an IP address from the ISP, enter the IP address of

the remote PC that will be managing the Gateway.

 If the remote PC obtains an IP address from a router that performs NAT, enter

the internet IP address of the remote router.

 If you do not know the IP address of the remote PC, enter 0.0.0.0. This is

useful if a number of different remote users require access to the Gateway or if

the IP address of the remote PC is unknown or changes frequently.

WARNING. This reduces the security of the Gateway, as it will allow any

remote PC access to the Gateway if they know the System Administration

password.

2 From the Remote PC

1. Ensure that the remote PC is connected to the internet.

2. The remote user opens a browser on their PC and browses to the Gateway using:

http://<the_Gateway_Internet_IP_Address>:8000

The Gateway’s Internet IP Address is displayed on the Remote Management

configuration page and in the status page.

3. The remote user must then authenticate with the system administration password

to access the Gateway’s Web interface.
