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 ?
