4.2.2
1:1 NAT routing
1:1 NAT enables the static mapping of an internal IP address from the LAN to an external IP
address from the WAN. An external host thus accesses an internal device as if both were in
the same subnetwork.
The password must be verified in order to define NAT rules and activate this feature.
4.2.2.1
Startup/activation of 1:1 NAT
Select the desired router mode on the “Services” web page, see also Section ““Services”
menu” on page 4-19. Then set the desired router configuration.
“1:1 NAT” menu
The settings for 1:1 NAT can be made here. In 1:1 NAT mode, the IP address area is
mirrored in other areas.
Figure 4-33
“1:1 NAT” menu
The start address of the address area in the WAN network that is to be mapped is specified
in the lower input field on the left-hand side (the IP addresses must not be used by another
device in the WAN network).
–
The length of the address area can be specified in the selection box by the number of
devices. By combining several address areas, any address areas can be defined.
Before activating 1:1 NAT, make sure that the WAN and LAN port have an IP address and
can therefore be accessed in the network.
