Hi, hope iam able to solve yours doubts.
if you want to introduce PF in your network as captive portal for Guest
registration and you have already a DHCP server running on your local network
serving yours Wi-Fi clients you do not need to run another DHCP server on PF
configuration, because PF is able to capture boradcast information coming from
others DHCP server.
So you have to configure your existing DHCP server providng the default gateway
corrisponding to PF server ip, in this way yours clients recive an ip address
when they access your wi-fi SSID that has as default route your PF
Captve-Portal.
this is a normal deploy for inline mode, so all the traffic pass trought your
PF server and it registers your device for the internet access. ( you have also
to configure the DNS server ).
If you want to configure an out-of-band deployment u can run a DHCP server on
your PF server and separete the Vlan for Registration proccess and Normal
internet Access.
So the first dhcp server on you pf server is needed for the registration
process after that you can set up the next hop as your already existing DHCP
server, in this way only the registration process pass throught the PF server,
when internet access is enabled correctly all yours clients will have a direct
connection to your AP/ROUTER.
Best Regards, Stefano.

Subject: [PacketFence-users] Inline Mode or VLAN Mode
Hi,
I would like some help in choosing between Inline Mode and VLAN Mode. As I was
reading about PacketFence I decided to implement it in the network especially
since it provides multiple features in one package.
>From time to time clients come and go in our company and they will require
>access to the Internet via wireless. This is were PacketFence comes in. As
>clients try to connect to the wireless network, they would be presented with
>PF registration/login page and once they enter the necessary information, the
>clients will connect to the network and eventually have Internet access. So in
>such case I am looking at a very simple wireless implementation.
The problem which I am trying to think out is regarding DHCP addresses. Since I
already have a DHCP service, how can I configure PF on a server that provides
DHCP IP addresses to clients connecting to the wireless network? For inline
mode I would require internal and management interfaces but how should these
work?
To summarize, I need the server that has PF installed to provide DHCP IP
addreses and at the same time the server recieves an IP address from the router
(which has DHCP service running). Hope I am not thinking too much!!
