Was I the target of a successful attack?

Would be a viable option to have indeed!

Is it possible to add a feature request for fail2ban in pfsense? I think this is important to prevent (D)DOS attacks leading to crash of service so my hope is that it is added to pfsense core and not as a package.

But it's already there. https://doc.pfsense.org/index.php/Sshlockout

Maybe not working then?? or enabled??

Erm… read the logs posted?
Jan 4 00:51:23 pf01 sshlockout[37765]: Locking out 222.186.56.43 after 15 invalid attempts
Looks damn well working.
P.S. None of this protects against DDoS. Not possible. Won't save your WAN from crashing.

Yes I can see that :) Thank you.

Not a way to configure it. And it seems that all though i disable it on the webgui then it doesnt get disabled in the console menu.
 -
The console is responsive ONLY when you enable and disable the sshd.
No can do via the gui.
-
No idea what are you trying to do with console. Serial console is not SSH.
-
I know…. but you can enable/disable it via the gui and via console.
It doesnt work disabling it via the GUI. Only via the console...
-
What's IT?!
-
SSH :)
-
Before disabling SSH via GUI:
# netstat -an | grep .22 tcp4 0 0 *.22 *.* LISTEN tcp6 0 0 *.22 *.* LISTENAfter disabling SSH via GUI:
# netstat -an | grep .22 #Re-enabling SSH via console:
# netstat -an | grep .22 tcp4 0 0 *.22 *.* LISTEN tcp6 0 0 *.22 *.* LISTENand checking back the GUI:

Doesnt work here…

This x 1000. I don't know why so many people incorrectly think that a simple firewall rule can mitigate a DDoS attack. I guess someone should tell the netops over at Sony and MS that they should add a firewall rule to stop their entire gaming networks from being blown offline like what happened a week or two ago…
-
It doesnt stop it or prevent it…
It handles it and doesnt interfere with normal services.
And dont let the security at Sony disturb you at night....if North Korea can get in, everyone can....

But depending on how your internal network is setup, the initial ddos on the wan could trigger a cascade of network activity which can slow the slower or under heavy load lans as well. With virtualisation becoming more common, the increased activity could also swap some cpu's as well.

Thats why you have sinkholes and load balanced servers ;)

When you can afford it.
Sadly I dont have GCHQ's or the NSA's budgets. ;)
