Please find the attach copy of the Network Diagram,

Thanks very much,

Hi,

One thing that jumps out at me are the way the routers are physically laid out. You have your 'primary' router connected to the pix and to the switches, and the backup router simply connected to the primary router. If the primary router goes down, then the backup router has no connection to the rest of the network.

If the purpose of the router labeled as 'backup' is for router redundancy, then I'd recommend connecting the switches to this router, and connecting this router to the firewall as well.

HTH,

Bobby

Single firewall tier with no back end protection.

I would add another FW besides the Perimeter FW.

Add a secondary FW tier to protect databases.
