You can walk thru the set up wizard and it will help you set up the router. Also there is information in the User Manual on how to set this up.
You want to use this at work? There maybe IPv4 services that may prevent this from being your main host router at work. Also there is not proxy features on this router. Proxy settings are set up on a server and routed via this server. Contact your IT dept about this.
You could use it as a wired AP maybe:
