I'm having an issue with Cisco Firepower Syslog, for some reason, I get the Syslog from the FMC with (null) in the place where the sender FTD IP or hostname should be.
I'm using a pure Firepower installation (not an upgrade from ASA) version 6.3.0 and I have another setup with the same problem of version 6.2.3.
The Syslog is looking like this:
Nov 6 15:05:02 (null) : %FTD-7-430002:Protocol: icmp, SrcIP: 10.255.0.130, DstIP: 10.255.0.2, ICMPType: Echo Request, ICMPCode: No Code, Policy: Default, ConnectType: Start, AccessControlRuleName: shay_traffic_test, AccessControlRuleAction: Allow, Prefilter Policy: Default Prefilter Policy, UserName: No Authentication Required, Client: ICMP client, ApplicationProtocol: ICMP, InitiatorPackets: 1, ResponderPackets: 0, InitiatorBytes: 98, ResponderBytes: 0, NAPPolicy: Balanced Security and Connectivity
Have anyone came across such a problem? Does anybody know how can I fix this?
