Rate-limiting per IP

Just 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 second.
- rate limit WAN client 1.2.3.4 to 10 ICMP packets per second.

  • UTM doesn't offer this currently. Just QoS for limiting which isn't quite what you want.

  • Ahoj Marian and welcome to the UTM Community!

    As Louis implies, QoS probably can solve the problem you have, but it won't be done in the way you're accustomed to.  WebAdmin is a GUI that manipulates databases of objects and settings.  A single change there can cause the Configuration Daemon to rewrite hundreds of lines of the code used to run the UTM.

    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.

    Cheers - Bob
