Parameter Description
NAT Table The NAT Table contains entries that inform the NAT function on the
type of translation and on which IP Addresses the translation should
occur. Each field of an entry row is described below:
Delete - Rows that have this checkbox checked will be removed from
the NAT table if the Delete button is pressed.
AutoIP - When checked this indicates that the External IP Address
field will be calculated based on the main IP Address of the RLX2-IHx
using the following formula:
Ext IP Addr = RLX2-IHx IP A offset,
where offset = 1 and is incremented for each row encountered that has
the AutoIP checkbox selected, walking down the table.
The main benefit of this feature is to enable an IP Address assignment
plan that only requires one IP Address setting on the RLX2-IHx,
allowing the configuration to be cloned to multiple identical networks
each with the same internal IP Addresses but differing only in the one
external IP Address that is configured.
Type - The type of 1:1 NAT translation to be done. Either 1:1 Src or 1:1
Dst must be selected. The appropriate IP Address fields in the entry
will be enabled depending on the setting.
Internal IP - The IP Address of a device on the internal network that
will be translated to the IP Address in the External IP field of this row of
the table, for packets going from Ethernet to wireless. The reverse
translation occurs on the destination IP Address of packets going from
wireless to Ethernet that match an External IP Address in the NAT
Table. If the entry is a 1:1 Src type then the destination IP Address in
the packet is translated to the Src IP Address in the entry.
Dest IP - The internal IP Address representing an external device.
When this IP Address appears as the destination of a packet going
from the Ethernet to wireless it will be translated to the External IP
Address of the entry. The reverse translation occurs on the Source IP
Address of packets going from wireless to Ethernet that match an
External IP Address in the NAT Table. If the entry is a 1:1 Dst type then
the source IP Address is translated to the Dest IP Address in the entry.
External IP - An IP Address on the external network that is translated
to/from internal IP Addresses that are in the NAT Table.
