    @NRgia said in Suricata on Pfsense: Your suggestion is preferred, but from I understood from you, nobody is interested or have the knowledge. Again thank you, for updating this package over the years. I'm sure there is someone here on the forum using the package that has the knowledge to maintain it. Another option if IDS/IPS is critical is to use the Linux package on a separate virtual machine or hardware appliance. Inline IPS performance would actually be very good using a Linux box (or even a FreeBSD box) with two separate NICs and configure true netmap hardware-to-hardware mode. That is many times more performant than the hardware-to-host mode that is required when using netmap within pfSense. Of course using a separate box would mean no GUI, but that's how the vast majority of the world uses Suricata already (without a GUI).

    @Antibiotic No it’s not possible with NtopNG as it is not a Netflow collector. You need nProbe for that which will “translate” recieved netflows into flows that NtopNG understands and can visualize (with very very little detail might I add as Netflows has no additonal information apart from sender/reciever and volume). The NtopNG package and the product in general is more geared towards visualising and recording traffic details from actual packet captures. This contains MUCH more metadata about the sessions than netflows (DNS names, protocol information and myriads of other things). But pffSense Plus has a builtin Netflow exporter if you have an external netflow collector on hand.

    @Gertjan Thanks for your reply – that’s also my impression. The point is: I don’t really see any lists right now that are actually “maintained” in the sense of being actively cleaned up, checked for dead domains, categorized, etc. That’s why my main interest is more about the demand: Would curated lists really be a game changer for admins? Would they be more helpful than what’s available today, or are most people already using other alternatives? If so, which ones? And from your perspective, what would be your expectation towards “community lists”? (e.g. reliability, update frequency, categories, fewer false positives?)

    @jhg said in NUT fails to start after 2.7.2 -> 2.8.0 upgrade: Interesting. I would have thought the initial reboot, which occurred as part of the upgrade, would have done the trick, but it took a second reboot, just now, to get things working. Glad you have it sorted. There was no difference in the output of usbconfig show_ifdrv at any point -- before or after unplugging/replugging the USB cable, nor after rebooting. ... Question: What would tell me whether or not a driver was loaded? If there were an attached driver, it should have shown up with the show_ifdrv command. If you use the command and look at the other usb devices, I think they will show attached drivers. I don't expect to see a driver attached to the ups, because there is a quirk that tells the OS to ignore that device (and not attach a driver). Look for idVendor and idProduct in the above output. The Vendor ID for your device is 0764, which corresponds to Cyber Power Systems, and the Product ID for your device is 0601, which is registered as "PR1500LCDRT2U UPS" (don't sweat an exact match for the name). You can see the quirk with the following command: [25.07-RC][root@fw]/root: usbconfig dump_device_quirks | grep 0764 VID=0x0764 PID=0x0005 REVLO=0x0000 REVHI=0xffff QUIRK=UQ_HID_IGNORE VID=0x0764 PID=0x0501 REVLO=0x0000 REVHI=0xffff QUIRK=UQ_HID_IGNORE VID=0x0764 PID=0x0601 REVLO=0x0000 REVHI=0xffff QUIRK=UQ_HID_IGNORE [25.07-RC][root@fw]/root: Your device is third on the list. The HID_IGNORE quirk says to ignore the device and not attach a driver. @jhg said in NUT fails to start after 2.7.2 -> 2.8.0 upgrade: You might consider adding this resolution to the release notes for 2.8. LOL... sorry, I don't have input to the release notes (I don't work here). While I wrote and maintain various packages, including NUT, I'm still just a volunteer. Most packages are actually written by volunteers.

    Anyone else happen to notice that when configuring BFD, if you create a peer and select a profile - after save, re-edit the peer and the Profile is not represented. It appears as "None". You have to check the raw config to determine if the profile was actually assigned to the peer. This is on 2.8.1 (all packages up to date as of the date/time of this post). UPDATE: if re-edit and save (without re-configuring the profile none to what you want) - the save will strip the profile from the peer.

    Hi All, I use HAProxy to redirect to a range of https internal resources, this works really well at the moment through the WAN where I have source limits set up, and I can connect to the internal resources from limited external IP Addresses. Given I have tailscale I would like to basically be able to put custom dns entries in to point these hostnames to my pfsense tailscale IP4 address (100.89.148.118) but I am not having any luck getting this working. At the moment, I am just trying to connect to HAProxy using https://100.89.148.118 but it is getting blocked by the firewall. Sep 11 11:55:58 tailscale0 Default deny rule IPv4 (1000000103) 100.89.148.10:53148 100.89.148.118:443 TCP:S I have tried with and without NAT redirecting internally to 127.0.0.1, and I also have rules set up to allow any traffic to and from my tailnets (defined in an alias) but I still keep getting these connections from my other tailscale machines being blocked on the pfsense machine. Can someone give me some pointers on what I am missing because I can see the requests are coming through to the pfsense machine, and in theory the rules should allow it through but I cant see why they don't. I do have tailscale ACL in place, but clearly that is not an issue as the requests are making it through to the firewall. 0/0 B IPv4+6 TCP/UDP TailNets * TailNets * * none Allow across Tailnets 0/0 B IPv4+6 TCP/UDP * * * 443 (HTTPS) * none Allow Tailscale IP4 I also tried adding a EasyRule but because the tailscale0 interface doesn't exist in pfsense it throws an error and won't let me add that rule. Appreciate any help or tips, Cheers.

    @HFADmin If it is no Site2Site-VPN then you don't need any gateways in the first place... If that is true but you want to monitor the connection then you could create dummy-gateways just to ping the remote ip-addresses.

    Never mind, I figured out the problem… it was Snort getting in the way. I had disabled Snort as part of my routine checks; but forgot to clear the blocks it had put into place. ::) Once the blocks were cleared and with Snort temporarily disabled Lightsquid installed just fine. :)

    I'm not sure I understand what you are trying to accomplish… For each group in Dansguardian (you can only create 3) you can specify multiple things (and I'm sure I will miss some). 1.) What sites are blocked based on a blacklist (plus allows via a whitelist) for URL's and sites 2.) PIC's based blocking 3.) Block rules based on weighted phrases in the content 4.) Grey list of sites that are allowed as long as they don't violate phrase blocking 5.) URL rewrite rules 6.) Content rewrite rules 7.) Blocking timeframes You can assign users to groups either by using an authentication mechanism (there are several) or by IP address.

    Hello joako, When you goto Snort and edit the Interface where you added the suppression, look at the Settings TAB, and find "Choose a suppression or filtering file if desired" The file listed here, should be the suppression list for the interface. There is a "View List" button, if you click that, does it show you the newly added Suppression's?

    There is a bug in the Snort binary with regards to SSL detection.  That might be what is happening here if the URL is https://.  You can Google some references to the bug by looking for "client HELO after server HELO".  This bug will hopefully be fixed in a later Snort binary release.  For now I recommend suppressing this particular alert. As BBcan17 mentioned, peruse the threads here in the Packages forum for advice on how to tune Snort by suppressing common false positives. Bill

    @BBcan17: @bmeeks: Have performed a "save" operation after disabling the writing to the system log and also tried restarting Suricata?  Look in the suricata.yaml file for the interface and see if syslog output is showing as enabled. Hi Bill, Sorry for sounding the alarm. I was looking at the General Settings tab for System logs which was not enabled. I have now disabled the system logs for Wan and Lan interfaces.  :o I don't recall the logs going to the System.log with the previous Suricata Package. I didn't play with the Suricata settings for awhile now. Here is what is in the yaml file for "syslog" grep -A4 -n "syslog" /usr/pbi/suricata-amd64/etc/suricata/suricata_30898_bce0/suricata.yaml 73:  - syslog: 74-      enabled: no 75-      identity: suricata 76-      facility: auth 77-      level: Info – 225:  - syslog: 226-      enabled: yes 227-      facility: auth 228-      format: "[%i] <%d> – " 229- I can't remember exactly when I enabled that, but it's been there at least since one of the earlier BETA releases.  Suricata has two distinct and different logging paths.  One is for alerts.  Those can go to syslog or not.  The other is for Suricata operations-related stuff like startup, shutdown, etc.  That always goes to the suricata.log file on pfSense, but can optionally go to the system log (syslog) as well if enabled.  That's why there are two different parts of the suricata.yaml file that reference syslog.

    Hi, I think you can export and import certificates and the CA from SYSTEM –> Cert Manager. Exporting Cert and Key and importing on the other pfsense machine. Or just make a backup of the running pfsense config and import this backup into the other pfsense. Perhaps you have the possibility to just import certificates and not all the other config. Unfortunately I cannot help you any further since I do not have any access to a pfsense machine anymore. My new company does not use pfsense .... :(

    Hi Mike, If you tune the rules, you shouldn't get too many False Positives (as you said, "probably one every two weeks or so"). With that said, I run Snort with the "Never Clear" setting, and just remove the ones as they come. I like this approach better because if you leave the Blocks alone, you will see a lot of repeat offenders and it will Block faster as its already in the Snort2c table. Snort is not a true-inline IPS so removing IPs will let some packets thru if they weren't already blocked. So tuning Snort is the best approach to managing a good IPS system. What kind of Dynamic IPs are you seeing? I submitted a post to add more Search Lookups to the DNS lookup page which can make it easier to diagnose IP addresses.. See below.. https://forum.pfsense.org/index.php?topic=73406.msg404649#msg404649

    @Atlantisman: I am on 2.1.3 i386, it looks like barnyard2 was having a problem with the SCADA rules and at least one other rule set. I took everything back to only VRT rules and barnyard started right up. Thanks. I can investigate the SCADA rules.  Those particular messages in your log post were just warnings, though.  They would not prevent a startup.  It was that fatal error trying to read one of the Emerging Threats Web Server rules that killed it.  The ET rules have had a few errors creep into them lately, and Snort (and now apparently Barnyard2 as well) can choke and refuse to start up if a rule with an error is encountered.

    found the issue. When the pkg gets re-installed via the system upgrade the conf file does not get restored. You have to go to the web ui of sarg in pfsense and click save and the conf file gets recreated. Heads up team! :)
