Symptoms
Implied rules are not enforced on DAIP gateway after an IP address change, or a reboot.
VPN Kernel debugs will show the lines: fw_match_implied_rules: Match implied rules returned NO MATCH;
and vpn_inbound_tagging_ex: fw_match_implied_rules returned 0;
IKE (port 500) traffic will be dropped with the error: dropped by vpn_drop_and_log Reason: Clear text packet should be encrypted;
If DPD is configured, the following lines will be seen in the vpnd.elg debug from the DAIP side. fw_kbuf_get_multik(instance: 0): ioctl(FWKBUF): Bad address find_sa_by_ike_peer: Error fetching IKE SA from kbuf [tunnel] send_dpd_notification_IKEv1: no IKE phase1 SA [tunnel] send_dpd_notification_IKEv1: deleting outbound SAs for 3rd party gw
The issue is not relevant if the DAIP gateway is an SMB device.
