Hello,
I hope you are doing well.
As a technical person I would recommend you one of our new small business routers which is the RV34x series, or one of the previous RV32x series.
In order to give you the best option based on your network requirements I will advise you to call our presales department which is dedicated for this types of questions
Small business presales number: 1800-553-6387
