Try editing the host file on your client to contain an entry that should direct
you to your PF box. IE: <IP of PF Server> google.com

Hi,
Wireshark on the client sees the DNS request packets going out but no reply. On
the PF server I can see the requests coming in but no reply from the PF server.
In fact pretty much the only traffic coming out of the PF server is DHCP and
SNMP traffic.
I tried configuring the external dns manually on the client but I don't think
this will work as there is no routing between the registration vlan and the
normal vlan
Nslookup from the packetfence server works fine.
Anything else I can check?

What does a wireshark capture on the client show? If you can capture the
traffic on the server as well, that would help.
Also, try manually setting your DNS to one of your other DNS servers (NOT PF)
and while on the registration vlan see if you can go anywhere.
You can also try doing a DNS lookup on the PF server using either dig or
nslookup.

Hi Jake,
The only firewall is iptables but that's configured by PF so would expect it to
allow DNS traffic?
I've checked and named is running and configured to run from the webui.
Below is my iptables.conf if that's any help?
Thanks
Adrian

Sorry if it sounds silly, but have you made sure that:
1) There are no firewalls blocking you and
2) Named is running on the PF box
Also, make sure that the config is set to run DNS, it is in the config tab ->
services in the webUI.

Subject: [Packetfence-users] Unable to access captive portal from registration
vlan
Hi,
I am stuck in the registration vlan 2. When my client connects it gets moved to
registration network and obtains a DHCP IP 192.168.2.10 with DNS server
192.168.2.1 (PF Server).
I then open a Chrome browser and type in www.google.com<http://www.google.com>.
As I understand it, PF should be running it's own DNS server on this VLAN which
will intercept the request and redirect to a registration page. But for me, all
that happens is the page times out saying unable to resolve the URL.
Does the PF installation automatically setup a DNS server or do I have to do
this manually? Also what is the URL it should be redirecting clients to for the
registration page?
Thanks
Adrian
