5.3 PORT FORWARDING
Port forwarding forwards all packets intended for one forwarding port on the gateway from the external networks
to be routed on a specified port on one of the internal BreadCrumbs. It is a kind of traffic redirection to some
other BreadCrumb, providing a particular service.
An example of this would be a web server running on a BreadCrumb. For machines or BreadCrumbs, attempting
to access this service, would know to send traffic to port 80 on the Gateway BreadCrumb. But in true sense, this
BreadCrumb does not host the web service. Some other BreadCrumb has the service running. So, a port
forwarding setting in the gateway helps forwarding all the traffic on its port 80 to the IP Address:port where the
web server is running.
5.3.1 SETTINGS
In BCAdmin, right-click on the BreadCrumb, where port forwarding is to be done and select Properties. Then
select the Forwarding tab. Add the range of ports on this BreadCrumb, on which if any traffic is received, will be
forwarded to some other BreadCrumb. For TCP or UDP traffic or both, select the corresponding check box. Then
enter the IP address of the BreadCrumb where traffic is to be forwarded. Also enter the range of ports for that
BreadCrumb. Check Enable to run this feature and the click the Add button.
For example, if a video camera is attached to a BreadCrumb with IP address 10.217.60.10 and is running on port
4001, and if the traffic for this arrives on port 75, then the settings for this should be –
Ext. Ports: 75 – 75
TCP: unchecked
UDP: checked
IP Address: 10.217.60.10
To Ports: 4001 – 4001
Enable: checked
