Outgoing firewall
The LT-4100 system allows the user to configure the outgoing firewall to only allow specific network traffic.
This permits the user to block outgoing network traffic so that IP data is only used for warranted actions.
The effect of this action is shown on Figure 51. Setting up the outgoing firewall is described in
on page 88.
Port forwarding
Port forwarding may be used on the LT-4100 system to remotely access IP data services running on user
equipment connected to the LT-4100 LAN port. This allows the user of the system to configure web access
for specific services using LAN ports on the LT-4100. On Figure 52 below a diagram shows how this is set up.
To be able to use port forwarding, the IP address of the system using the LT-4100 LAN port should be
statically assigned. This is explained in detail in
on page 88.
