I currently have security network consisting of five physically separated locations connected. Each location has 50 to 100 devices requiring IP addresses. These devices are network cameras, alarm control components and access control devices.
Each location has either a dual Sonicwall TZ 215's or dual 2400's in failover configurations. For additional redundancy three of the locations also have two ISP's.
Each location is a subnet. The subnets are connected using VPN tunnels configured between each Sonicwall. The Sonicwall on each subnet also provides DHCP and other services needed for its subnet.
Subnet Configuration:
???.???.100.1 Primary Location
???.???.101.1
???.???.102.1 Secondary Location
???.???.103.1
???.???.104.1
There is now a need to configure Windows 2012 Network services, DC, DHCP, DNS, File Services Keeping in mind that this system will remain a closed network with minimal requirements for internet access (upgrades, utility services, etc...).
Would like to have high availability (load balancing and failover) spread between Primary and Secondary locations. Will only have 15 to 20 Users Logging on and accessing video servers and other security assets.
