I'm the IT admin for a small business with about 25 people.
We recently moved to a new office and bought a Cisco SR-520 router. The initial setup and config was done by the company that sold us the router and did our internal wiring.
I have no experience with Cisco products at this point, and don't know where to start learning how to use this router and adjust the config as needed.
Does anybody know a good place to start?
