I have a Juniper SRX550 router. Port 0/0/0 is Internet. 0/0/2 is 172.16.64.1/18, and 0/0/3 is 172.16.128.1/18. I also have the Juniper to do DHCP for the two networks.
Cable goes from 0/0/2 to port 1 on a Netgear ProSafe XS716T (172.16.64.2/18). Then 0/0/3 to port 1 another Netgear ProSafe XS728T (172.16.128.2/18). Then, I have a third Netgear switch (172.16.64.3/18) that trunks with the other .64 switch. All 3 switches are on VLAN 1.
What I'm trying to do is, when a user connects to the 172.16.64.3/18 switch, I want them to get a 172.16.64.0/18 or 172.16.128.0/18 DHCP address depending on their login credentials. Is this possible?
