Looking into setting up a guest network. We would like to give a certain amount of our internet bandwidth to the guest network and setup DHCP on the ASA for the quest network. The guest network needs to be totally segmented from our corporate network.
Do you have a proxy server on your network?
You could create a separate zone/interface for the GUEST users giving it a lower security level as the inside. For DHCP have a look at:
"We would like to give a certain amount of our internet bandwidth to the guest network"
I don't think the ASA supports this inherently. There are third party plug-ins for this tough.
No you can actually, have a look at:
So the configuration would be like to plug in from a switch port to the ASA port and set up DHCP for the ASA interface on the ASA and use QOS to port throttle the interface?
So the configuration I described looks accurate? Come out of the switch port that is assigned to the guest network vlan into the interface/port on the ASA that will be for the guest network. The ASA interface/port ip address will be the default-gateway for the clients correct?
You don't need to configure any vlans/sub-interfaces unless you require more zones than the interfaces built-in to your box (5).
You just choose any unused interface and set it up like this:
interface gig 0/2
For the host to set the interface address as their default-gateway would I need to use "dhcpd option 3 ip 192.168.100.1 interface GUESTS" assuming 192.168.100.1 is the ip address for interface g0/2? And for the host to route out my outside interface (to get to the internet) would I need to set a route?
I would assume that is required (setting the default gateway) for a properly designed network.
For the internet you just need a default route on the box:
route outside 0 0
From what I have looked through the DNS and WINS for this type of setup are global so the guest network users would be using the same DNS and WINS server as the clients on the corporate network. Are you familiar with this?
You can even skip DNS for the guest users. All they do is access the proxy server and the proxy server will resolve DNS for them.
So they will proxy off my corporate internal proxy server? Wouldn't you have to touch the vendor PC's to add the proxy info?
What if I didn't want users on the guest network touching any servers on my nerwork. Could I point them to an external public DNS server? Do you suppose this would work?
Would this point the users on the guest network to the following DNS servers?
dhcpd dns 18.104.22.168 22.214.171.124 interface vendor
As far as nating goes I will need to set that up right? The guest users network will probably nat off the same interface that my corporate network is (the outside) interface. Right?
