Sorry for the latency.
Indeed this variable was set to 1.

I didn't test in routing mode

Hello everyone, I made some security testing on OPNsense 19.1.

I've configured it with two interfaces in bridge mode. The firewall is placed inside Hyper-V.
On the one hand, the first interface is conected to VM with hping in flood mode. On the other, on the second interface, I've a VM with wireshark. The firewall is configured to block every packets.

I observed that on reboot of the firewall, it become permissive for about 0 to 1 second on startup.

Is that an issue that you already known ?

Hello,

I made performance testing last time.
I configured OPNSense in bridge mode with 2 client.
Those clients forward their traffic through the firewall.
When I ping without stressing the firewall, I got about 1ms of latency.
But when I ping the firewall and generate a traffic to the maximum capacities of the firewall (about 1.5Gbps) my latency is two times less than not charged, about 0.5ms.
Any ideas of what is happening ?

Thank you ;)

PS : I'm using Hyper-V 2012 R2

Thank you for your help ;).

I'll give a try !

Hello,

I'm using OPNSense in an architecture that is not connected to Internet.
I would like to use the IDS/IPS and especially import rulesets.

Is there a way to do that without Internet ?

Thank you :)
