17.1 Legacy Series / How to prevent SSH bruteforce, DOS attacks

« on: March 11, 2017, 01:37:23 pm »

Hi all,

Looking for a quick advice here - would anyone know if there is a way to prevent/limit number of SSH login attempts similar to the one you can do with IPtables? (let's say to only allow 3 consecutive attempts per minute)

And on the same note - is there an easy rule to control/limit/drop syn packets to prevent DOS type of attacks?

Regards,
Matt

17.1 Legacy Series / [SOLVED] All settings are gone after reboot

« on: March 10, 2017, 11:28:02 pm »

Hi all!

I'm new to the OPNsense so hoping for a bit of an advice - I have just installed it as a VM on VirtualBox and for some reason after each reboot, it keeps erasing all settings (interface IPs, installed plugins etc.). Each time it starts, it looks like it is going through the same loop - "Default interfaces not found -- Running interface assignment option." - no matter what I do.

I found a suggestion to install os-boot-delay plugin but again - this is gone once firewall gets restarted

Any idea why would that be happening?

Regards,
Matt
