A static lease could not be added because there was no free space in the internal leasing
table. The message also shows the IP address of the static lease that should be added.
Adding static lease IP=<x> failed, wrong IP address
A static lease could not be added because the IP address indicated did not match the
network address. The message also shows the IP address of the static lease that should be
added.
8.4.15 Network address translation
The firmware of the device is able to perform network and port address translation (aka
NAT/PAT) in order to route traffic between a local (internal) and a global (external)
network. This feature can be used, for example, to give another device in the local network
access to the gateway's cellular modem Internet connection (global network). The device
must be connected to the Ethernet interface of the Fieldgate FXA42 for this purpose.
The following operations can be performed here:
• Enable NAT service
• Configure internal and external network interface
• Configure maximum number of mappings. Maximum number of mappings means
incoming and outgoing connections that can be routed.
IP forwarding is implicitly enabled because it is needed in order to use the
NAT function. If NAT is later disabled, IP forwarding will not be automatically
disabled. IP forwarding can be disabled in the network settings.
Dynamic mappings
Dynamic mapping is used to enable devices from the local network to access the global
network. Requests from the local network will be given the global IP address of the
Fieldgate FXA42 and the replies will be routed to the respective local device.
You have to configure how many minutes dynamic mappings will be valid (time to live).
