as we are proceeding building our network, some questions are arising, which I don't know simple answer to. I prepared some visual slide for you to help you orientiate in our current situation ....
When we started with internet providing, we started reselling some ADSL connectivity in smaller regions. So because of that historical reason, when we got our very lucrative AP place, we started to interconnect the nodes and because of that we went with natted nodes. But I am not sure it is correct design and have some questions in that regard:
Here's my slide:
Our nodes are connected to main router on 5GHz. Local natted networks for clients are on 2.4GHz. So - from the main router point-of-view, we can't see the end users, only the nodes.
Can we say, that such design is bad ... or sufficient and used? I am not sure if it would be better to see users directly on main router, would it have any advantage? From the shaping point-of-view, we would shape user on his nearest node, as why to flood radios with unnecessary transfer? Of course that would be possible with routed network too ....
My other questions follow:
1) Is it a good overal network design to build natted instead of routed network?
- what if two clients from two neighbour network would like to communicate? Separate IPs? Tunnels?
2) How can I ping from J/10.0.0.60 to N/10.0.5.2? (We want to use winbox from our PC shop (10.0.0.60 IP)
- need I define a static route? How?
- isn’t there a chance that reply will be lost, as N network contains 10.0.0.x subnetwork too?
3) How to forward (route) Public IP we got from ISP2 to e.g. N/10.0.5.2 network interface?
4) two neighbour interfaces can’t have compatible IPs, right? How to achieve that M network IP would be on 10.0.5.x network too?
OK, I would appreciate getting at least some questions/concerns answered/brainstormed ....
I know that some stuff can be found in docs, I read them, believe me, but if I would understood, I would not loose my time preparing the slide and asking questions :-)
Thanks a lot,
