4.10 Configuring NAT Settings
You use the NAT tab to specify the Network Address Translation parameters of a RLX2-
IHx radio. This feature maps a set of external IP Addresses to internal 'private' IP
Addresses in a 1:1 manner.
When NAT is enabled, the RLX2-IHx Ethernet port becomes the default gateway for the
internal private network and the wireless interface provides access to the external
network. The IP Address configured for the RLX2-IHx via the
Basic Settings
Tab must
valid on the external network. The IP Address used for the internal network, and which
must be configured as the default gateway on all devices on that internal network, is
configured via the
NAT
tab in the
LAN IP Address
and
LAN Subnet Mask
fields.
There are 2 types of NAT entries:
1:1 Src
entries and
1:1 Dst
entries. All devices on the
internal network that wish to access or wish to be accessed from the external network
must have a 1:1 Src entry in the NAT table to translate their internal IP Address to an
external IP Address. This means that the most devices that an RLX2-IHx can support on
the internal network is 16 (max NAT Table size), when NAT is enabled.
