I have the following network below. The router is a Juniper SRX 550 with 3 networks. 0/0/2 (currently disabled) is 172.16.64.1 /18, 0/0/3 is 172.16.128.1 /18, and 0/0/4 is 172.16.192.1 /18. The Juniper provides DHCP for these networks also, and this is working fine. Then I have 3 Netgear ProSAFE XS728T switches, 172.16.64.2 /18, 172.16.128.2 /18, and 172.16.192.2 /18. All 3 switches are on VLAN 1. I know to fix this, I can connect the AP to the 172.16.128.2 switch, but I HAVE to connect the AP to the 172.16.192.2 switch.
The problem is that, I have a Ubiquity WiFi AP on 172.16.128.3 /18, and it's connected to the 172.16.192.2 /18 switch. Because of this, I can't connect to it from the 172.16.128.0 or the 172.16.192.0 switches. This looks like a routing issue. How can I fix this? I HAVE to connect the AP to this switch.
If I connect the WiFi AP to the 172.16.128.2 /18 switch, everything is fine. I can connect to this WiFi from the 172.16.128.0 and the 172.16.192.0 devices, I have access to the Internet
