We are redesigning our network from scratch. We are hosting our devices at a datacentre which is around 500-700 mtrs away from the HO. There will be a fiber running from the DCR to the HO. Total Users on the network will be around 70-100 and they will be in a windows domain environment. I am planning the following at the DCR:
1. Install a cisco ASA for firewall and VPN services.
2. I will install a Cisco L3 switch. I will be creating 01 vlan for the Servers, 01 vlan for the Data Circuits and 01 vlan for clients at the HO.
Issue: I am not sure what switch should I install at the HO? Currently there is a unmanageable 3com switch at the HO. Also should I have separate subnets for the HO users and the restaurants users or should I put them all on one class B network.
I have attached the network diagram.
Appreciate your feedback.
