Is it possible to add a proxy to an Antmner S3? I want to place the Antminer at work, but there is a proxy I have to go through. I can see where to put the DNS information, but not where to put a proxy name. Any help would be great.

Using your employer's electricity for personal gain is likely to get you into some trouble. If you have a legitimate reason to consider such a setup (for example, if your employer pays a lower, business electricity rate than you do), you can ask your employer for permission.

If you need to go through a restrictive firewall, you can try a project such as the OnionPi (Adafruit), which uses a Raspberry Pi (35$) to tunnel all incoming connections through Tor. You will need to change the Wi-Fi antenna in the original project with a USB to Ethernet adapter, as the Antminer needs to connect via Ethernet, and besides, running a Wi-Fi router inside your company's network will get you into trouble.
Tor itself can connect through a proxy with the
HTTPProxyAuthenticator configuration directives. If entry nodes are on the firewall's blacklist, you can use the BridgeDB to get some circumvention servers that use encryption and obfuscation to evade blacklisting.
