IPS Exception not working

Hi,

I have problems with IPS in UTM, the UTM handles IPSEC traffic with VEEAM backup and Replication, and triggers this:

2019:09:10-02:55:51 mail-2 snort[13000]: id="2101" severity="warn" sys="SecureNet" sub="ips" name="Intrusion protection alert" action="drop" reason="MALWARE-OTHER Ransomware SamSam variant detected" group="500" srcip="192.168.11.20" dstip="192.168.10.31" proto="6" srcport="902" dstport="53906" sid="48814" class="A Network Trojan was Detected" priority="1" generator="1" msgid="0"

192.168.11.20 is a VMWARE ESXi server
192.168.10.31 is a Veeam Server (Windows)
 
I have added this exception in the affected UTM:
 
But nothing helps :-(

  • Hi Martin,

     

    If this is a specific rule that is always triggered (48814 given this log), you could try to modify this rule to either disable it or change it to alert in the advanced tab. 

     

    Regards,

  • Hi Karl-heinz,

     

    Thanks for pointing out ;-)

    Only thing is, that if another host/server behind the UTM, get's the SAMSAM attack, then it would just ignore it, therefore I hoped for the host exception to work, but there is a problem with UTM in that matter I see.

    Tried to change from IPSEC to RED Site-2-site, just for fun, but of course, the issue remains :-)
