      @jamesadams How big is your average package and how many do you see on your WAN connection pr. second??

      10gbe is a lot of things depending on the scenario on which to implement it.

        @cool_corona for the package it's a little too technical for me I couldn't tell you

        And my wan connection :

          @jamesadams It important to know the load and what packages IDS/IPS is supposed to run on it afterwards?

          10 gbit routing is easy.... 10 gbit IDS is difficult.

            What hardware do you have?

            what hardware ? Sever, modem...

              I'll give you an example. I have a 500/20 Mb connection. I recently upgraded from 75/10, but my usage hasn't changed. Is pfsense working harder? Perhaps for short bursts, but overall no.

              PfSense running on Qotom mini PC
              i5 CPU, 4 GB memory, 32 GB SSD & 4 Intel Gb Ethernet ports.
              UniFi AC-Lite access point

              I haven't lost my mind. It's around here...somewhere...

                I don't yet know which IDS / IPS I'm going to run, because I haven't yet configured a firewall ๐Ÿ˜

                @JKnott I would say the maximum that I happen to use at the same time is 3-4GB

                  I assume the modem is capable of providing a 10 Gb connection, as is the NIC in the server. However, that says nothing about the performance of those devices. One thing that affects this is all the buffers used in the computer. The packets can be stuffed into a buffer faster than the system can handle. TCP responds to that by slowing down the throughput. So, your hardware may be capable of a 10 Gb connection, but not sustained 10 Gb traffic. Again, it boils down to expected load and what the hardware is capable of.

                  This question is similar to "how high is up"?

                      The point is without data about such things as intended load, hardware performance, etc., it's impossible to answer your question.

                        @jknott the only thing I can tell you is

                        My modem : Freebox delta s (provided by my internet operator)

                        My serveur :

                        • Ryzen 9 3950X

                        • 64Go of ram

                        • Network card: Asus XG-C100CF SFP+

                        Maximum consumption seen 3000 mbps

                          Real world traffic (imix) can be forwarded (routed not filtered) at 10Gb with Xeon D class chips according to Netgate. Also according to Netgate the same traffic is going to be limited to ~6Gb when filtered (firewalled).

                          So, the lesson to be learned is real world 10Gb performance (LAN<->WAN) with pfSense as it currently exists is not possible with any reasonable hardware you would want to use as an on 24/7 device. Of course, you could build something that could do that but the cost would be a lot of power consumption and the required fan-noise to keep it from melting down. I guess you could water cool... but would you want that running 24/7?

                          Netgate mentioned that part of the move to pfSense plus would be improvements to pf. That would filter up to FreeBSD and be of benefit to all. Also, TNSR was developed for the purpose of moving traffic loads greater than 10Gb.

                          An ASIC based HW router (think big expensive Cisco/Juniper and the like) does 10Gb and beyond routinely.

                              For some comparison points see the higher end models here:
                              https://www.netgate.com/products/appliances/
                              The 1541 shows:
                              L3 Forwarding: 15.41 Gbps
                              Firewall: 6.10 Gbps
                              (10k ACLs)
                              IPsec VPN: 2.81 Gbps
                              (AES-128-GCM / AES-NI)

                              Also, higher speeds are what TNSR is for, Netgate's other product. (the second table)

                              "Can't find a firewall for my massively high speed connection" is definitely a "first world problem"!

                              Pre-2.7.2/23.09: Only install packages for your version, or risk breaking it. Select your branch in System/Update/Update Settings.
                              When upgrading, allow 10-15 minutes to restart, or more depending on packages and device speed.
