Dell 1U R210 server Sophos pfsense firewall Atheros Wireless access point small rackmount

I bought this server cheap on ebay. This a perfect server for a small wallmount rack. I installed Sophos UTM with an atheros PCIe wireless network card. I wanted to make the firewall with integrated wifi. This card is capable 300MB 2.4ghz and 5ghz. This setup also works with pfsense. I've already verified with my last build.
