![]() Outbound traffic is similar except in that case the kernel and firewall would see the packet first, then the Suricata engine and finally the NIC. Notice how the Suricata engine sits between the actual NIC driver and the remainder of pfSense's kernel. Here is a simple diagram illustrating the path an inbound packet (from Internet to an internal LAN host) takes. ![]() The packet never makes it that far using inline IPS mode. No benefit at all to having the IP address stored in the firewall table. If the same attacker comes by again, the packets will just be dropped again. There is no "remembering" of dropped packets. Dropped packets never go anywhere past the NIC (looking from the point of view of being located outside on the WAN side of your firewall looking in). ![]() Suricata will either pass on or drop packets. With inline mode, every single packet first must go through Suricata before the operating system and the firewall even see the packet. The snort2c table is not used at all for inline mode blocks. For starters, inline mode does not use the packet filter firewall nor any of its tables. Inline IPS mode is markedly different in operation than the old legacy mode. Would I expect to see these items stored in the snort2c table for an hour based on my settings or is that setting for the legacy mode? Are drops not inserting themselves into the firewall table to prevent the client from coming back for a defined period? One feature coming to the SYNC tab is the ability to selectively sync just parts of the configuration instead of the whole done the steps in the first post and the alert.log is now reflecting DROP and the web interface as well. Now that the big stuff is in, I can go back and work on those lower priority things. It was low priority while the rest of the package was converted to Bootstrap and the inline IPS feature using Netmap was being added. One other item that will get some love in the near future is the XMLRPC Sync tab. A future update will incorporate a new Bootstrap-compatible progress bar provided by Steve Beaver from the pfSense team to show the download progress of the rules package tarball files. The UPDATES tab now provides a little more visual feedback, but it is not yet where I want it to be. Rules update process on UPDATES tab appears to not complete sometimes, and the lack of some visual feedback confuses users. Number of entries to display value on BLOCKS tab not initialized in some circumstances resulting in no blocked hosts being displayed even though blocks exist in the pf table for legacy mode operation.ġ1. Number of entries to display value on ALERTS tab not initialized in some instances.ġ0. ![]() Automatic log management does not default to " yes" on LOG MGMT tab.ĩ. Pass Lists created on the PASS LIST tab are not available in the drop-down for selection on the INTERFACE SETTINGS tab for a Suricata instance.Ĩ. Editing/saving of Custom Rules not working on RULES tab.ħ. Dashboard Widget not properly handling multiple interfaces (row sorting gets off).Ħ. Suppress List deletion is allowed for an assigned list, but it should be prevented and a warning message displayed instead.ĥ. Disabling of rules by clicking the icon on the ALERTS tab not working and resulting in just a page reload.Ĥ. Rule suppression using " by address" icons on the ALERTS tab results in garbled HTML resulting in the tooltip text being incorrectly displayed instead of the appropriate icon.ģ. The ALERTS, BLOCKS, LOGS VIEW and SID MGMT tabs are missing some or all breadcrumbs in the header.Ģ. This update corrects a number of user-reported bugs in the GUI package.ġ. The Suricata package for pfSense 2.3 has been updated to version 3.0_6.
