Operation modes and rule configuration
5�1 Mode NAT router
In NAT router mode, the Microwall connects the island net-
work to the Network 2 port (green) via a fixed IP address of
the higher-level network to the Network 1 port (yellow). The
operating mode is comparable to many standard DSL routers,
which connect the home network to the Internet using only
one public IP address.
The IP addresses of the island hosts are replaced in the super-
ordinate network by the local IP address of the Microwall and
are therefore not visible in the intranet at any time. The island
IP range can be selected completely freely in NAT mode. Even
several islands with identical IP ranges can be connected to
the company intranet simultaneously in this way. An interven-
tion in its routing concept is not necessary.
Activate the NAT router operating mode via the menu tree
under Firewall settings -> Operating mode and define the
handling of ICMP echo requests/replies (ping) to the local in-
terfaces and the forwarding of other ICMP datagrams..
The Save button activates the NAT Router mode and the corre-
sponding rule set is loaded.
