Re: [PacketFence-users] Issue with dhcp sending wrong DNS in clustered mode

[Simon Gottschlag]

Hi,

I think PF works with DNS interception in inline mode, forcing all queries to 
123.123.123.123 or something like that and by that, forcing it to the Captive 
Portal.
In my case, DNS doesn’t work after registration when the PacketFence-nodes are 
the DNS servers.

Either I need to get the packetfence nodes to act as DNS servers, or I’ll need 
to use other DNS server.

What would you like to know about the environment? I’m not sure what is 
interesting in the configuration?

Regards,
Simon Gottschlag

When a device is in registration vlan, the DHCP assigned dns server is the PF 
server.  This is so they can redirect to the captive portal.

Im not sure how it operates in inline mode.

What is your setup?

I’m using the latest version of PacketFence (ZEN) and have setup a cluster.
Registration works, and after that I’m able to ping the internet (example 
8.8.8.8).

My problem is that I’m not able to resolve anything else. The DHCP server 
(packetfence server) are sending the cluster nodes IPs as the DNS servers, even 
though I’ve specified another one in networks.conf.

Are the nodes in the cluster meant to handle all DNS queries? If not, what do 
you think could be the problem?

Hi All,

It was an issue with the inline detection.

@fdurand solved it!

[PacketFence-users] Issue with dhcp sending wrong DNS in clustered mode

[Simon Gottschlag]

Hi all!

I'm using the latest version of PacketFence (ZEN) and have setup a cluster.
Registration works, and after that I'm able to ping the internet (example 
8.8.8.8).

My problem is that I'm not able to resolve anything else. The DHCP server 
(packetfence server) are sending the cluster nodes IPs as the DNS servers, even 
though I've specified another one in networks.conf.

Are the nodes in the cluster meant to handle all DNS queries? If not, what do 
you think could be the problem?

Best regards,
Simon Gottschlag
