: Changed values of menu
1:1 NAT configuration
Note:
The
private
IP address 192.168.1.254 now is the new IP address of the Router from the perspective of connected de-
vices at the LAN port. All devices connected to the LAN port have to be configured in the private IP range 192.168.1.0
with subnet mask 255.255.255.0.
The 1:1 NAT (address translation) is working in that way that every address of the private Class C network will be
changed to the corresponding public address.
