UBNT EdgeRouter LAN Config Issue

Ok guys I'm utterly confused. So when I go back to the Edge Router, add the 10.10.3.1 and 10.10.4.1 to the interface for my lan, ...
I might have missed this, but why do you have multiple networks on a single LAN?

I am under the impression, all subnets should only be set up on the windows server directly, not on the router.
Set up in what way on the Windows Server? Why does Windows Server need configuration for subnets it is not on?
What's the purpose of the different subnets?

So the Router options need to be change on each scope to have the correct gateway. You shouldn't need to have multiple gateways for each subnet. Do you have the guest subnet VLANs accessible from the Server?

He only actually has two subnets.
10.10.0.0/22 and 10.10.4.0/24 -

10.10.0.0/22 and 10.10.4.0/24Then that still is not good.

Exactly, and he's shown that he has many DHCP scopes scooped up into a SuperScope. all of that needs to be deleted and a new single zone for the 10.10.0.0/22 needs to be created.

@krisleslie You need to reconfigure this network right now because you are overlapping networks which are included in the first network.

No he isn't. He has a large subnet and a small subnet.
The large subnet has multiple gateways assigned on various computers for unknown reasons, but it is just 1 large subnet.

I didn't do the math.. I was assuming 10.10.0.0 and 10.10.4.0 when in /22 overlaped, but they don't.

Looking back at the config in the first post - it appears that whoever set this up felt that they needed more than /22 on the single network, so they tossed on the 10.10.4.0/24 to give 256 more addresses to that space - why they didn't just go to 10.10.0.0/21 I don't understand.

Deleted.

@dashrender Because that would take it to 10.10.7.255

https://i.imgur.com/QzDJIga.pngSure you did, but it doesn't actually show you the full size of the network... i.e. 10.10.0.0-10.0.3.254
...............
look at the picture again....

yeah, I just noticed that last line.

https://i.imgur.com/QzDJIga.pngThat makes more sense. So is just bad DHCP configuration.

Ok so this makes a lot more sense. Heads up guys im not the network specialist so its really outside of my thought processes. Thats a weak point of mine and I am studying to get the network +.
With that said, so I can make sure I understand is first the router was incorrectly setup on that one interface. To fix that, I will need to remove the other gateways and ultimately have just 10.10.0.1/21 instead of 10.10.2.1/22. If i were to remove it during business hours, some wireless devices eventually didnt have a gateway and thus no connection to the internet. But removing them will cleanse that problem after clean up the Windows Server DHCP service.
So to fix the DHCP server, we need to remove each scope and super-scope and recreate only one scope as 10.10.0.0/21 which negates whatever way this was setup originally. The static ips we had assigned should still work and I just need to make sure we are excluding them from the scope.
Lastly reboot and pray and possibly with adult bevarages.

The biggest issue i have is i normally have a well defined sheet that i structure for the entire network. Its not as good as ive seen some folks on here or spiceworks but it was easy enough to read and have a sense of knowing everything had a place.
The way my associate setup this network, hell i cant even make heads or tails of it. Truth be told he cant either its just wrote down in a notepad in scribble last time we discussed this.
-
I disabled the guest wifi to reduce the suck until the issue is resolved. I’ll reenable it soon and put it on its on network.
-
Sounds good. Though I would add 10.10.0.1/21 now and leave the firewall alone until you make the other changes. This will enable everything to keep working until the other changes are made.
Also, look at the lease time on your DHCP server. Set it to something like 4 hours for now. Assuming it's the default 8 days or whatever MS sets things to, changing it to 4 hours (or less) will allow you to make changes and have clients pick those changes up quickly. But once you make this change, you'll need to wait 8 days before starting anything to make sure all DHCP clients have the new shorter lease time. After things are stable, you can increase the lease time back to whatever you're happy with.
