https://community.sophos.com/utm-firewall/f/network-protection-firewall-nat-qos-ips/100546/rate-limiting-per-ipJust evaluating UTM 9 (as VM) and I am unable to find a way how to rate limit (in pps) a particular IP. Examples: - rate limit LAN client 10.10.10.10 to 100 UDP packets per second. - rate limit WAN client 1.2.3.4 to 100 established connections per seconden-USTelligent Community 12https://community.sophos.com/thread/365485?ContentTypeID=1Tue, 20 Feb 2018 11:30:23 GMT4be5eb7d-caa4-4ff5-8e60-8f9463545a35:18ec67b1-eb3e-48a6-b53a-4ef18bcd6306BAlfson<p>Ahoj Marian and welcome to the UTM Community!</p> <p>As Louis implies, QoS probably can solve the problem you have, but it won&#39;t be done in the way you&#39;re accustomed to.&nbsp; WebAdmin is a GUI that manipulates databases of objects and settings.&nbsp; A single change there can cause the Configuration Daemon to rewrite hundreds of lines of the code used to run the UTM.</p> <p>Although one could tinker at the command line to solve the problem, better would be to help us understand the problem in order to point you in the right direction.</p> <p>Cheers - Bob</p><div style="clear:both;"></div>https://community.sophos.com/thread/365214?ContentTypeID=1Sun, 18 Feb 2018 02:02:05 GMT4be5eb7d-caa4-4ff5-8e60-8f9463545a35:5639cfea-94ff-4b43-bd79-7e96d39b2959Louis-M<p>UTM doesn&#39;t offer this currently. Just QoS for limiting which isn&#39;t quite what you want.</p><div style="clear:both;"></div>
