Configuring a Radio - Detailed Configuration
User Manual
The 1:1 Dst type entries allow a device on the internal network to address a
device on the external network using a local internal IP Address. This entry type
is not often used, but does allow configuration of devices on the internal network
to be agnostic of any external IP Address, relying on the NAT table to map a
'standard' set of local external IP Addresses to their actual external equivalents.

Description
This enables or disables the NAT function of the RLX2-IHx. NAT is only
available if the RLX2-IHx is in Repeater or Bridging Client mode. In
Master or Client modes the NAT Tab is disabled. If NAT is disabled,
then no Network Address Translation (NAT) occurs and the RLX2-IHx
operates in normal Repeater or Bridging Client mode. When NAT is
Enabled the source IP Address and optionally the destination IP
Address of packets going from the RLX2-IHx Ethernet to the wireless
interface are translated according to the NAT Table entries for those IP
Addresses. The reverse translations occur for packets going from the
wireless interface to the RLX2-IHx Ethernet.
The LAN IP Address becomes the IP Address the RLX2-IHx uses for
its Ethernet interface. When NAT is enabled the RLX2-IHx operates
like a NAT router and this IP Address must also be the default gateway
for the internal private network. The default for this IP Address is
192.168.1.1 and should be changed if a different subnet is desired for
the internal network.
The LAN Subnet Mask defaults to 255.255.255.0 to match type C
address default for the LAN IP Address. It is important to set the subnet
mask correctly on the RLX2-IHx and that it matches the subnet mask
configured in each of the Ethernet devices on the internal network.
This button is used to add a new entry to the NAT table. When pressed
a new row appears at the end of the list in the table view. Up to 16
entries can be present in the NAT table. Attempting to add more will
pop up an error message dialog. Once added the fields of the entry
must be set according to the type of translation and the IP Addresses
to be translated. Note that the entry is only saved once the Apply
Changes button is pressed.
This button is used to remove selected entries from the NAT table.
When pressed any entries that have the checkbox in the Delete column
checked, will be removed from the list. Once an Apply Changes is done
the entry is permanently removed. If the webpage is refreshed prior to
doing an Apply Changes, then the original NAT entries will repopulate
the list.
