We have a PacketFence cluster setup at our main office that services 17 other 
sites as well.

I am trying to setup the registration VLAN at the remote site. What I have done 
thus far:

1.       Create a routed network in PacketFence with the registration type and 
enabled DHCP on it.

2.       Setup DHCP relay on the Layer 3 switch at the remote site and pointed 
it to the PacketFence Cluster IP in the Registration VLAN at the main office

The PacketFence cluster will respond to DHCP requests of client on the 
Registration VLAN at the main office, but not remote sites.

If I use the tcpdump command to view packets coming in, I can see that the DHCP 
requests make it to the PacketFence cluster, however the PacketFence cluster 
does not send a DHCP reply.

If I give a device a static IP address on the registration VLAN on the remote 
network, I can ping the PacketFence cluster IP (on the Registration VLAN) and 
get to the Captive Portal, so firewalls aren't an issue. PacketFence just isn't 
sending any replies to DHCP.

I also tried restarting all the nodes to make sure any services that need 
restarting after the change have been restarted.

What piece am I missing?
