Re: configration

Main issue in design of this model is ip addressing. Here is my opinion for ip addressing. Assign different subnets for each branch office with /16 subnet mask. Say for eg 10.1.0.0/16 , 10.2.0.0/16, 10.3.0.0/16, 10.4.0.0/16 so that you wouldn't problem when you add additional hosts in Branch offices. Then take 10.5.0.0/16 and assign the ip address in this range for Port 1 , Port 2 of the firewaal (Transparent Mode) and Ethernet interface of HP router. You will obviously assign a public ip to wan interface of HP router and do Port Address Translation(PAT) on HP router.
