We currently have 5 subnets that connect back to one central location. To simplify things we have subnet A, B, C, D, E and subnet A is our central location. Not necessarily a need to communicate between all subnets and just need each to communicate back to Subnet A.
Subnet B is connected via T1 (Cisco Router 1700 Series)
Subnet C is connected via T1 (Cisco Router 1700 Series)
Subnet D is connected via MPLS (Addtran managed by Qwest)
Subnet E is connected via MPLS (Addtran managed by Qwest)
Current firewall are Sonicwall
We have fiber transports being installed between the subnets and is basically a Metro E or VPN line setup. We are not planning to use any of the above hardware and also do not want to convert everything to a flat network.
Looking for some different ideas and opinions for hardware to use. Want to keep it simple and cost down.
Would also like another opinion on hardware that could be configured for fail over to a redundant connection, but may not go down that road.
