I see a few things that concern me.
1. Entirely bridged network:
Your current configuration allows any one customer to bring down
your whole network. Consider changing the switches to routers at sites 4
and 5. By creating logical segments (subnets) in your network, you limit
the effects of broadcasts and packet storms.
2. Internet and Customers on same side of Main Router:
Having two internet feeds and most of your customers on the same
AP can have serious consequences. This setup hinders proper bandwidth
management, reliability and security. Consider using 3 or 4 APs instead
of two at your NOC. Use the site 3 APPO to feed site 4 then add another
AP as a backhaul for site 1 and 2. Connect all units to the Mikrotik
router so that all of your customers must pass through the router.
3. Asking for help and asking for advice:
<soap box>
At the risk of sounding too harsh, don't ask a peer group such
general questions as "What do I do now?" if you can avoid it. Of course,
we are here to help, but you should not build your network based off of
our advice. The best way to build a solid, scaleable network
infrastructure is to study the technologies and research you options.
When you can ask questions like "I would like to segment my network and
have decided to use a routed infrastructure, what are some options too
look at that will also allow BW management and usage tracking?" then we
know your are really trying.
</soap box>
Good luck, ignore the ranting, and email me at
support(at)tomhaynes(dot)net if you have any more questions.
