7.4.3 NAT
This function conceals non-public (internal) IP addresses. These addresses are not forwarded
to the Internet. PCs are thus invisible to the Internet as the data is exchanged completely via
NAT.
The internal company LAN appears as a single IP address to the Internet. All access operations
between the LAN and the Internet are processed via this address and various port numbers.
At the same time this prevents any IP connection attempts (including attacks) from the Internet
to the corporate LAN. Only connections released with the Explorer function "NAT" can be
reached from the Internet.
