Appendix F. IP forwarding, NAT, Virtual Server
IP forwarding, NAT and Virtual Server allows redirecting IP requests:
-
IP modem connection (for instance incoming connection from
TConnect
)
-
Ethernet ports
The typical use is a remote access to an IP camera connected to the Ethernet port of the RTU: you dial the
RTU with
TConnect
and display a HTML page containing a link to the IP address of the camera.
This redirection feature requires enabling Advanced IP Configuration. As a matter of fact, if an Ethernet
port of the RTU is connected to a LAN, and the IP forwarding is activated, anyone can access the LAN from
a modem connection!
We provide several security levels, to enable these features:
1.
From RTU properties, ‘Protection’ tab,
the general access security of the
document must be activated with a
HEXADECIMAL code of 4 characters
To
generate login and password
corresponding to the code you have to
use « Password generator » (see chapter
17.3).
To improve protection, we advise against using the same codes forGlobal code and
Advanced IP configuration
