I am assisting my friend with a school project. Basically I had a few questions. Here is the scenario.

7 branch offices connected to a central office with dedicated T1 lines.
1 network for data and separate for guest wireless network at each location.
All internet comes through proxy at central location
Around 60 hosts at each location

The switch for the data network is plugged into one Ethernet interface and the WAP is plugged into the second Ethernet interface of the router at each location.

IP Scheme example:

Branch 1: Data 192.168.1.0 /24 Wireless 192.168.50.1 /24
Branch 2: Data 192.168.2.0 /24 Wireless 192.168.51.0 /24

Questions:

Should he put Cisco ASA firewalls behind each router at the remote locations?
If so, how do you configure the Cisco ASA if two Ethernet ports are used on the Router?

Are they using dedicated MPLS networks or just internet T1s and you are providing the VPN?

Easy answer would be "no," you simply configure PBR and ACLs on the routers so that guest networks never touch your Data network. ACLs are more of a firewall function, but it comes with every Cisco router so depends on what capabilities your router has. If the router is simply serving a router function then you need firewalls.

If you wanted to put ASAs at each location, you would put it between the router and your data network (or switch in this case.) That way you can prevent the guest network from any location from accessing your data network by using the firewall to block it.

That's the thing about I.T. there's a million ways to do things...
