    I will look into this one.  There were lots of changes in the ALERTS tab code for the Bootstrap and inline IPS updates.  Looks like something got messed up with the intermixing of HTML and PHP code.

    @vbentley:

    Hopefully, in response to CVE-2016-1345 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20160330-fp it will get bumped to 2.9.8.2

    Snort on pfSense is NOT compiled with the "–enable-file-inspect" flag, so it should not be vulnerable according to the security bulletin.

    Updates to the pfSense binaries for Snort and Suricata only happen after those updates are posted in FreeBSD ports.

    I don't use any commercially provided VPN's so I'm not entirely certain where your problem is. However, perhaps terminating your side of the VPN on a new pfSense interface (LAN2/OPT1 whatever) introducing an additional hop may help if you want specific Snort rules (or none) for this interface only.

    It's not the answer you want to hear, but you have to make that decision yourself.

    When the IDS detects an intrusion, what you do about it is your decision. Generally, I trust my IDS and act on what it reports. If the intrusion can be safely blocked without breaking any services then it stays blocked. If blocking breaks stuff then I usually capture the traffic in wireshark and take my time to check what is actually happening.

    If I can't block the intrusion because it is from a provider I will contact their sysadmin. Usually, when evidence is presented to the sysadmin the intrusion stops. If it doesn't stop, chew whoever is insisting on using the provider by letting them know how much it is costing to deal with the provider's bad behaviour and insist on a compensatory discount at contract renewal or change of provider.

    @coachmark2:

    Do we think that this is something to do with this bug or is it the HP 7506 not passing some sort of traffic between the two boxes that needs to be passed?

    That has nothing to do with this. Worst case, this causes the config sync to fail to happen, so nothing changes on the secondary. Also not likely it has anything to do with your network. Rough guess, maybe you're setting the CARP IP to the same IP as the LAN IP of the secondary, or something similar where the presence of the VIP breaks the IP of the secondary. Start a new thread describing what you're doing and what you're seeing.

    The problem was the /tmp and /var space.  Due to NanoBSD implementation, defaults were in place 40Mb and 60Mb.  However, the box I'm running it on is running AMD G-T40E dual core w/ 4G RAM.  I increased the size of the /var and /tmp to 500 MB each and reinstalled SNORT packages.  Took SNORT a bit over 5 minutes to start up, but it's been running with out issues with Balanced IPS policy and Emerging Threat rules enabled.

    Hi Howard:

    I responded in another thread on this issue.  This one may take some time to fix.

    Thanks for the update. Is this something that might be examined during the development or in a subsequent release? Is there something I can configure locally?

    Best Regards,

    @crester:

    Hello.
    After the new campaign of radsonware I have received few custom.rules to add to snort (from intel security, see bellow)

    Also, make sure you check the new track/blocklist from abuse.ch

    @Kryptos1:

    Hello Bill,

    Thank you for the reply. I found where the snort configuration files were. If someone modifies the suppress list texts with a text editor, what would be the command to restart/reload snort so that text file is reread and loaded? I'm trying to learn and document all the commands necessary to manage snort/pfsense remotely over ssh.

    Chris

    There is a shell script (/usr/local/etc/rc.d/snort.sh) that you can execute to restart Snort. Just call that script with one of these arguments:  start, stop or restart.  I suspect restart is the one you want to use.  The shell script will impact all of the configured Snort interfaces.

    The last supported version of Snort for 2.1.x hasn't been supported by Cisco for signature updates in quite some time and hence the package was removed, since it could no longer function.

    There are no known stability issues with IPsec in 2.3. There is still a status problem we're working on where sometimes the status pages hang, but it doesn't affect functionality. Starting a thread on what you were seeing there would be your best bet.

    I found several other errors this past Friday in the new Suricata GUI code.  They result in some parts of SID MGMT working incorrectly.  There are also problems with saving changes to a few things on the FLOW/STREAM and APP PARSERS tab.  I have a comprehensive fix almost ready to post that addresses these and a few other cosmetic issues.

    Sorry for the bugs, but converting a package to Bootstrap is a major change.  In the rush to completion we missed some things in testing.

    By the way, this parameter (max-synack-queued) is now configurable in the GUI for an interface on Suricata 3.0 in pfSense 2.3-BETA.

    Your IP address definitions are incorrect.  The error message is essentially telling you what's wrong.  You have "not this IP" ranges that are more general than your "this IP" ranges.  What you need to do is invert your ranges.  Make your "this IP" range more inclusive than your "not this IP" range.  Posting your rule with the actual IP address ranges might help us troubleshoot this with you.  The rule is on line 2256 of the file /usr/pbi/snort-amd64/etc/snort/snort_15257_igb4/rules/snort.rules
