Note
This tab is only available in the client mode.
On this WBM page, you define the translation list for communication from the global to the
local network. Per WLAN client (NAT gateway), 60 entries are possible.
Description
The page contains the following boxes:
● "Interface" drop-down list
Interface to which the settings relate. Can only be selected if the device has several
interfaces.
● "Traffic Type" drop-down list
Specify the protocol for which the address assignment is valid. TCP and UDP frames
must have parameters set separately.
● "Global Port" input box
Enter the global port. Incoming frames with this port as the destination port are
forwarded. If the setting is intended to apply to a port range, enter the range with start
port "-" end port, for example 30 - 40.
Note
If the port is already occupied by a local service, for example Telnet, a warning is
displayed. In this case, avoid using TCP port 23 (Telnet), port 22 (SSH), ports 80/443
(http/https: reachability of the client with the WBM) and UDP port 161 (SNMP) as global
port.
● "Local IP Address" input box
Enter the IP address of the node in the local network.
