Siemens SCALANCE M-800 Getting Started page 15

In routing mode
In this example, three different IP subnets will be interconnected via the SCALANCE M826.
For this connection, there must be a one SHDSL interface of a device in the role of CO and
the other in the role of CPE. Since the SCALANCE M826 devices operate in routing mode,
there is a division into external and internal networks. This means that the SHDSL interfaces
and the Ethernet interfaces are located in different IP subnets. In this mode, the security
functions (IPsec VPN, firewall, NAT/NAPT) are available.
Figure 1-5 SCALANCE M826 in routing mode: The network nodes are in different IP subnets. The SHDSL interfaces are
connected together via the company's own 2-wire cables.
