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

19.1 Legacy Series / Security issue : Bridge is permissive on reboot
« on: September 11, 2019, 10:48:38 am »
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 ?

Hardware and Performance / Less latency when firewall is stressed
« on: June 07, 2019, 05:25:24 pm »
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

Intrusion Detection and Prevention / Manualy import rulesets
« on: March 13, 2019, 02:02:51 pm »
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
