| SDSL Router | | | +-----------------+
| 4 static IP |===1 <> firewall+bridge <> 2===| DMZ Hub

+-------------+ | | +-----------------+

+-------------+ | | +-----------------+
| ADSL Router |===3 <> firewall+routing <> 4===| Intranet switch
|==>...
| dyn IP | | ^ | +-----------------+
+-------------+ +------------5-----------+
|

| WLAN Transceiver |
+------------------+
The routers were attached to the wrong interfaces/firewall chains.
