In the last part, part 1, we configured our OpenWRT device, got it to emit two(2) Access Point SSIDs (insecureWiFi & secureWiFi), created two(2) VLANs to separate traffic frames, and created a trunk to our PoweConnect switch! Wow!
For this part, part 2, we will be creating another VLAN Trunk from our Dell PowerConnect switch to our Linux router, designing and configuring some Firewall rules.
I set out on this home project with the intent of providing wireless internet to friends and family when visiting. I wanted to provide internet without allowing any malicious clients from consuming all my bandwidth and/or crippling my internal home network. There are many Wireless Access Points(WAP) that are capable of broadcasting multiple SSIDs. Cisco makes a few from their Aironet series, however they seem to be pretty expensive. I settled with a Netgear WNDR3700 after reading a few posts on hardforum.com that had success running OpenWRT.
OpenWRT is an third-party firmware designed for consumer based Access Points, such as Netgear, Linksys, Dlink, etc. OpenWRT adds many additional features, including the two features I needed. Support for 802.1Q trunking and gives the ability to run multiple SSID wireless signals.
