Set up an alternative private IP range
To provide BT Fusion support, it is strongly recommended that
you use the default private IP range of the BT Hub. The default
private IP range is 192.168.1.x.
If you need the BT Hub to supply an alternative private
IP address range, go to the BT Hub Manager.
• Go to your Internet browser
• Type in
bthub.config
• Click on Configuration pages access
• Go to Configuration, then Advanced, then Network
• Change all of the values in this option to your chosen IP range
You can only use the permitted private IP class A-C address ranges
10.0.0.0./8; 172.16.0.0/12 and 192.168.0.0./16
• Click on Submit
Set up a static IP network
If you have a static IP broadband service and you need to set
up an email server, file server, web server or VPN with the BT Hub,
it is recommended you follow the instructions below for port
forwarding or DMZ.
Forwarding IP traffic to a particular computer
• Go to your Internet browser
• Type in
bthub.config
• Click on Configuration pages access
• Go to Configuration, then Advanced, then Router
• Use the port forwarding rules to establish a direct link.
For example, to set up a web server, forward all traffic to port 80
to the internal IP address of your web server computer
To find out the internal IP address of a particular computer
• Go to Start, then click on Run
• Type in cmd and click OK
• At the c:\> prompt type in ipconfig and press return
To set up an FTP server on the same network forward all traffic
on port 23 to the FTP server computer and so on. Your server
computers remain behind the BT Hub firewall.
The BT Hub DHCP server will automatically register any PC in your
network that has a static IP setting within the
192.168.1.x subnet.
For example, a static IP of
192.168.1.10 in your network will be
recognised by the BT Hub. The addresses
192.168.1.0 and
.1 and .255 are reserved and cannot be used.
DMZ
If you set a particular computer in the DMZ you are placing it outside
the protection of the firewall. For example if your router WAN address
has a static IP of 217.34.10.40, a computer 192.168.1.10 situated
in the DMZ can be directly addressed by the WAN IP. You should
proceed with caution as computers placed in the DMZ will be subject
to intrusion. The DMZ is provided for specific applications only
and you should consult a computer security expert before using
this facility.
