Connection to internet
After discussing multiple options, we decided to go with Dommel: fast access, cheap, no caps, no ports blocked. We went with the lower cost - lower speed option, with the idea that, if we want more, we can always upgrade.
Note: We are currently not using anything of the web- and mailservice below.

We also have a connection to the wireless antwerp network Wireless_Antwerp
LAN @ Whitespace
You can find the backup config files here: File:Network configurations v1.7z
The Modem: DLink DSL-2740B
We use this modem for the adsl connection to Dommel. Beware when you configure the modem: once every x restarts, the adsl stops working. Waiting a few minutes and restarting it again seems to fix it...
Dommel uses dhcp to give us an ip (although the ip itself is static). Because the modem randomly fails to do the dhcp, we configured the modem as bridge (translate adsl to ethernet). The router (totoro) now does the dhcp.
Totoro: the router
The cisco RV082 router serves as the main router. It has the following functions:
- dhcp server which gives out ip's in the range 172.22.32.50-200 (also gives the googleDNS as DNS servers)
- 2 WAN connections: One to Dommel, one to Wireless Antwerp.
- static ip configured for gatekeeper 172.22.32.14 => 00 00 24 c8 99 cc
- static hostname configured: gatekeeper => 172.22.32.14
The load-balancing and failover is configured so that:
- all traffic from LAN ip's in range 172.22.32.0-200 (includes the full dhcp range) goes default through dommel's ADSL(wan2)
- all traffic from LAN ip's in range 172.22.32.201-254 goes default through the Wireless Antwerp uplink (wan1)
- If one of the interfaces goes down (interfaces are being checked by pinging 220.127.116.11), all traffic goes through the other interface

Cisco AirPlus 2.4 ghz Wireless Access point
There are a few of them around the space. You can reset the AP's to factory settings by holding the reset button for 20 seconds. They provide 2 wireless network:
- WPA key: unicorns
- Is connected to Totoro
