Hello, my name is Chris Adams. My business partners and I recently opened a 
coworking space in Baton Rouge, Louisiana, and I'm looking for some advice 
on network setup. Any suggested companies or people that have an 
understanding of coworking and/or are recommended by space owners are 
welcome as well. A little bio: We've been open since July 2017, and I have 
tried multiple solutions found online without finding the solution that I 
believe is right for me. I'm hoping to get advice or information from other 
owners and space managers to help determine our space's precise needs, and 
we are looking to hire for services and/or professional advice. However, we 
are a young company, and I'm trying to waste as little money as possible 
and avoid paying for things I do not need.

*Our Current Setup:*

   - Nexudus Software to manage users, billing, etc.
   - Mikrotik router with hotspot for Nexudus wifi checkin
   - 1 Managed Ubiquiti Unifi 24-port Switch 
   - 1 Managed Ubiquiti Unifi PoE Switch 
   - 4 SIP VoIP Polycom Desktop Phones
   - 1 SIP VoIP Polycom Soundstation 5000 Phone
   - Xerox WorkCentre 6515 DN MFP connected via LAN
   - One on-site Ubuntu server
   - Ezeep for printer management w/ Nexudus integration
   - Five VLANs (all w/ dedicated subnet & DHCP):
      - Our admin VLAN w/ dedicated SSID
      - Hotspot VLAN w/ dedicated SSID
      - Client1 Admin VLAN w/ dedicated SSID
      - Client1 Staff VLAN w/ dedicated SSID
      - Client 2 VLAN w/ wired ethernet access only
   
*Current Setup Notes:*

   - I hired an IT engineering firm based in Austin to help remotely 
   because I was having problems with the MikroTik/Ubiquiti combo (i.e. Unifi 
   software completely stopped working after a couple of weeks, MikroTik 
   hotspot was buggy) and they fixed those issues at a pretty hefty price. 
   They hinted that they though my network setup was unusual, but I wanted to 
   be sure of exactly what needs to change before hiring them (or someone 
   else) to assist with the process.
   - I have a Unifi Security Gateway which was replaced by the MikroTik. 
   USG was purchased before I chose Nexudus as my management system. 
   - All users are running either Windows 10 (desktop & mobile), Mac OSX, 
   and have various mobile devices.
   - I chose VLAN setup because my clients brought their own 
   printers/copiers and wanted to be able to share the printers and files with 
   each other without the risk of unauthorized access. 
   - The MikroTik/Nexudus Hotspot is set up to block traffic between 
   clients connected to that subnet. I could program everything EXCEPT the 
   Polycom SoundStation to bypass hotspot authentication and connect to the 
   internet on the hotspot network. I did this to prevent users from 
   connecting their devices directly to outgoing ethernet ports in the phones 
   to bypass hotspot authentication.
   - I have no ability to track and charge for copies or received faxes on 
   the WorkCentre. I mistakenly thought the model I purchased supported 
   document codes and accounting features. It does have user management with 
   very limited permission options, a very disorganized event log, and support 
   for common authentication protocols such as LDAP.

*Plans and Goals:*

   - We're switching from Nexudus to Proximity Space soon, which will 
   eliminate the eZeep integration and various other features built into 
   Nexudus. I have two old Microsoft Server boxes with decent storage, ram, 
   and processors that I would like to use for file and print servers (with 
   central user authentication, group policies (shared folder size limits, 
   print limits and policies, etc.), and a CRM. 
   - I think the server should be Linux based due to the required 
   compatibility with Windows, Mac OSX, Linux, and mobile device clients. I 
   don't want anyone to lose their current local user accounts on their 
   systems. I'm hoping there's a possibility for my server user to match their 
   local user and work together. 
   - I tested JumpCloud's Directory as a Service on my machine, and it took 
   over my local user account which worked out great except for the fact I can 
   no longer manage the local user account from my PC. I'm not sure members 
   would like that. JC also offers Radius as a Service, which I thought may be 
   beneficial to me in some way.
   - Is there an option other than VLANs and/or separate subnets to 
   segregate network sharing? Do VLANs require a dedicated subnet? My server 
   will not ping a client in another VLAN/subnet, but the client can ping my 
   server from VLANS outside of the hotspot. I haven't tried to ping my server 
   from clients in the hotspot.
   - I would like to have a dedicated VoIP network that only allows either 
   voice only traffic or mac address authentication.
   - Security is a major concern for me. I do not understand linux's 
   command line firewall configuration or MikroTik firewall configuration. QoS 
   setup is a priority for me in the future as well.
   - It's not a must, but I would like to be able to control the public PC 
   in our conference room. I do not want users to have access to any settings 
   or be able to install programs, etc. on the machine. Automatic deletion of 
   downloaded files would be nice, too.

*Short version - *I would like to control which clients can access certain 
directories and printers, have a central user management system for 
file/printer access control policies, have users use the same login on the 
printer as they would on the network and wifi, account for all pages 
printed, copied, and received via fax based on color or black and white ink 
usage, VoIP network that blocks everything but the phone/voice traffic, 
central control of the public PC in our conference room, and user-friendly 
QoS & internal and external security configuration.

Please let me know if I am misunderstanding something or left out 
something. We're growing faster than I thought we would, and I want to 
ensure my members are happy and my network runs smoothly. I can't begin to 
tell you how much I would appreciate any type of feedback, advice, or help. 
Thank you so much. 

Sorry if I used any incorrect terminology and my lack of expertise on this 
subject. Also, sorry for the long post.
