Feature #2860
Updated by Victor Julien over 5 years ago
Suricata doesn't detect part of IKEv2 traffic. Some devices (Mikrotik for example) allows to start IKEv2 traffic on port 4500 (not affected by NAT Traversal enabled). In the case of UDP 4500 for IKEv2 selected, this IKEv2 traffic is not detected by Suricata. The traffic is detected as normal UDP traffic, but not recognized as IKEv2.
