This summer we installed a MX100 firewall. At the time we only had the enterprise license and not the Advanced license. We had an old Barracuda 310 webfilter in place. Well we recently upgraded to a spectrum 200Mps/20Mps pipe and if we plug directly into the Spectrum modem the speeds are right where they are supposed to be. However on the network they are still a little bit over 100Mps down and they should be 200Mps down. So we assumed that the barracuda might be to blame because it is only rated at 100Mps throughput. So we upgraded to the Advanced license on the MX (we were going to do this anyway) and removed the cuda. And, the network throughput is still only a bit over 100Mps down.
Now I know that the MX100 is doing a lot but is it possible that this higher end firewall can not support speeds over 100Mps?
Solved! Go to Solution.
Thank you for the fast response I know I have not done any traffic shaping on the unit at all. I am glad to see you are getting great speeds so it is possible.
I will check into the traffic shaping settings to see what can be tweaked. But nothing was setup out of the box.
No worries, if that isn't the case, then id check things like DNS, if that checks out then maybe you've got a bad link somewhere limiting you to 100mbps.
Try setting the shaping to 200mbps and see if that helps. Some modem expects the router to do the shaping or else packet will be dropped. When doing a throughput test from the LAN, that device might try to generate more than 200mbps and when the modem is only capable of 200mbps will start dropping packets causing the overall throughput to drop. Might not be exactly you situation but wroth trying.
