Gustav was very professional and patient working with me on upgrading my network configuration; Segregating my network; setting up vlans; Configuring routes and firewall rules; Implementing Trunks between routers/switches. He scheduled a time that worked for both of us and was promptly available. He explained everything in detail, remoted in and made the changes, and gave me plenty of opportunity for input and questions. I could not be happier with the end product. 10/10 would work with him again in the future.
