While troubleshooting a DHCP relay issue, you run a fw ctl zdebug drop and see the following
output: ;[cpu_1];[fw_0];fw_log_drop: Packet proto=17 10.216.14.108:67 > 172.31.2.1:67 dropped
by fw_handle_first_packet Reason: fwconn_init_links (INBOUND) failed; Where 10.216.14.108 is
the IP address of the DHCP server and 172.31.2.1 is the VIP of the Cluster. What is the most
likely cause of this drop?
A.
A link collision due to more than one NAT symbolic link being created for connections
returning from the DHCP server back to the VIP of the Cluster.
B.
A link collision due to more than one NAT symbolic link being created for outgoing connections
to the DHCP server.
C.
An inbound collision due to a connections table check on pre-existing connections.
D.
An outbound collision due to a Rule Base check, and dropped by incorrectly configuring
DHCP in the firewall policy.
