The following table describes the labels in this screen.
Remote Host
This field displays the source IP address (on the WAN) of inbound IP packets. Since this is often
a wild-card, the field may be blank.
When the field is blank, the Zyxel Device forwards all traffic sent to the
External Port
on the
WAN interface to the
Internal Client
on the
Internal Port
.
When this field displays an external IP address, the NAT rule has the Zyxel Device forward
inbound packets to the
Internal Client
from that IP address only.
External Port
This field displays the port number that the Zyxel Device “listens” non the WAN port) for
connection requests destined for the NAT rule’s
Internal Port
and
Internal Client
. The Zyxel
Device forwards incoming packets (from the WAN) with this port number to the
Internal Client
on the
Internal Port
(on the LAN). If the field displays “0”, the Zyxel Device ignores the
Internal
Port
value and forwards requests on all external port numbers (that are otherwise unmapped)
to the
Internal Client
.
Protocol
This field displays the protocol of the NAT mapping rule (TCP or UDP).
Internal Port
This field displays the port number on the
Internal Client
to which the Zyxel Device should
forward incoming connection requests.
Internal Client
This field displays the DNS host name or IP address of a client on the LAN. Multiple NAT clients
can use a single port simultaneously if the internal client field is set to 255.255.255.255 for UDP
mappings.
Internal Client Type This field displays the type of the client application on the LAN.
