[PacketFence-users] PacketFence 8.3 not populating node IP Addresses even though it is receiving the DHCP packets.

[Brenek, Benjamin via PacketFence-users]

Hi All,

I am trying to get node IP address to populate within PacketFence and for some 
reason they just don't seem to be doing so, even though PacketFence is 
receiving the DHCP packets from my Cisco router.

Configuration:


  *   PacketFence 8.3 Cluster (3 Servers)
  *   Cisco router which has two IP Helper Addresses.
     *   First IP Helper Address points to a remote DHCP server which hands out 
the IP addresses
     *   Second IP Helper Address points to PacketFence cluster IP
  *   Running tcpdump on all of the PacketFence servers, I can see that the 
Cisco router is sending the DHCP packets
     *   08:51:00.945765 38:90:a5:ed:98:fb > 00:50:56:91:6d:d3, ethertype

     *               END Option 255, length 0
     *               PAD Option 0, length 0, occurs 10
  *   What is weird is that OS detection is working, so PacketFence is at least 
getting and reading parts of the DHCP packets.

Any help here would be great, as this issue has been bugging me for a few days 
now.

Thank you,

Ben
