A Multimedia Home Network – Layout

Two key components are building the core functionalities:

• The WRT54GL WLAN router provides PPPoE connectivity to the Internet provider’s DSLAM, Firewall and SIP ALG, relays all DNS requests, DHCP service for clients with non-static IP addresses,  and basic WLAN access.
• The DNS-323 is a Network Attached Storage device with 2 harddisks. It provides storage space for Sat TV recordings of the two Dreambox Sat TV receivers. Furthermore it keeps the complete Audio CD library for remote access as well as other data files.
  A cron job starts a backup script which creates daily snapshots.

Both core components run under Linux with alternative FW versions. This allows customization and extensions.
