· Communication area
After the equipment is installed, it is recommended to investigate the communication-enabled area by using
the station.
· Security enhancement using a firewall
Security can be enhanced by combining an upper-level protocol having the encryption function, such as IPSec
or PPTP, and a firewall.
Example of configuration using a firewall
Intranet
Station
Access Point Access Point
Firewall
1. Separate the network (intranet) to be protected from the network having access points, and place
a firewall between them.
2. Install protocols having the encryption function, such as IPSec or PPTP, in the stations and
network resources (such as shared servers) in the intranet. Define the system so that
communication is always performed through these protocols.
3. For communication between stations and network resources in the intranet, the firewall filters
protocols to prevent any protocols other than IPSec and PPTP from passing through.
