Masquerading
It is possible to mask the IP address of any incoming IP connection using the masquerade option. By ticking
on the
‘Use masquerading’ box the LT-4200 will replace the source IP address of the incoming IP connection
with the IP address of the LT-4200 terminal LAN port before it is forwarded to the configured destination.
This is shown on Figure 107.
Masquerading may be used if the PC/user equipment being the target of port forwarding rules has another
preferred route to the internet e.g. via a VSAT solution etc. In that case the PC will
– if masquerading is not
enabled – chose to send its replies via that route instead of via the LT-4200. By using masquerading the
host is forced to send its replies via the LT-4200 as the LT-4200 IP address is the only visible IP address to
the target/host.
