comment SMB Server & Switch
To add some perspective for you. Imagine you segregate the switching perfectly and you only share an internet connection. One virus infection can get your IP address blacklisted across many email providers. When your tenant suddenly can't send email because of one of your computers is infected, what is your plan? Because your tenant will start using words like 'lost business' and 'damages'.

Ideally, you only share the room. No equipment cross over at all. The point of a wiring room is to have all your wires meet at one point in order to maximize flexibility with cross connections. Sharing equipment/networks/telecom is something that should be avoided. This goes double when you don't have expertise in this area.

comment Routing between many systems, no first hop
Smells like a masking issue. Can you add your route tables? At least for the main router?

comment Access server using IP on another interface
OK I think I understand your question better now. It's just that you can't reach the public IP successfully from the LAN. What happens when you try to tracert to the public IP from the LAN?

comment Why is Windows 7 not following all routes?
You've got an issue at layer 2. Your computer can't ARP for machines on the same broadcast domain. That's why adding a static route works. When you add the static route, you ARP the gateway successfully and the gateway can ARP the destination for you. To work correctly the ARP should be peer to peer. The router interface your computer is connected to is probably providing a layer 3 boundary (routed) rather than just a layer 2 segment (switched).

What are your DNS settings? If you want this change across all services, make the public IP resolve for the my-domain.com server.

comment Disk performance below expectations
The drives would have to be removed from the array to test. The default array settings might not be optimal for your use. The stripe size and caching which can impact I/O performance dramatically.

Do you have an ifcfg-eth0.0 file in /etc/sysconfig/network-scripts/?

The switch could be adding the tags. What does your VLAN topology look like?

comment Can't reproduce arp non-response issue with spoofed packets
Lorin, very interesting issue. The requests appear identical. I'm curious what the conversation looks on the other endpoint. What ARP traffic does 10.40.0.5 see?

comment Issues with connecting to network resources after segmenting network
Firewalls don't tend to cause chronic issues, but lets not rule anything out. Take a problematic printer, and do a continuous ping to it from an affected station. Do you see packet loss? Also what do the packet counts look like on your switch ports, is it possible that we have a switching/routing loop somewhere?

comment Issues with connecting to network resources after segmenting network
Few questions to get started: What are the IPs/Netmasks/gateways of the various networks? What is the route table on the Mikrotik, and what interfaces are configured on it?
