I need to help troubleshooting DHCP on my registration VLAN. I used tcpdump to see if DHCP packets are making it to the packetfence server and they are:
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on eth0.21, link-type EN10MB (Ethernet), capture size 262144 bytes 09:24:40.932786 IP 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from 00:15:5d:83:cc:03 (oui Unknown), length 300 09:24:44.861274 IP 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from 00:15:5d:83:cc:03 (oui Unknown), length 300 09:24:48.827419 IP 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from 00:15:5d:83:cc:03 (oui Unknown), length 300 09:24:56.778174 IP 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from 00:15:5d:83:cc:03 (oui Unknown), length 300 However, PacketFence isn't offering an IP to the client. Here is my networks.conf file (I used the WebUI to configure the networks): [10.0.22.0] dns=10.0.22.252 split_network=disabled dhcp_start=10.0.22.10 gateway=10.0.22.252 domain-name=vlan-isolation.example.com nat_enabled=disabled named=enabled dhcp_max_lease_time=30 fake_mac_enabled=disabled dhcpd=enabled dhcp_end=10.0.22.246 type=vlan-isolation netmask=255.255.255.0 dhcp_default_lease_time=30 [10.0.21.0] dns=10.0.21.252 split_network=disabled dhcp_start=10.0.21.10 gateway=10.0.21.252 domain-name=vlan-registration.example.com nat_enabled=disabled named=enabled dhcp_max_lease_time=30 fake_mac_enabled=disabled dhcpd=enabled dhcp_end=10.0.21.246 type=vlan-registration netmask=255.255.255.0 dhcp_default_lease_time=30 If I statically set an IP to the client (10.0.21.101/24), I can ping the client from PacketFence and the client can ping PacketFence. Any idea what I am missing?
