I'm struggling I'm new to FreeBSD and trying to get up and running an IPFW firewall on my FreeBSD VPS.
I don't want to setup any NAT but only firewall filter rules.
IPFW config file
# Block IP
ipfw table 1 add 126.96.36.199/8;
$cmd 160 deny ip from 'table(1)' to me
$cmd 161 deny ip from me to 'table(1)'
root@mydomain:/var/logs/nginx# ipfw table 1 list
Why do I get lines like this in the NGINX error and access logs?
I have a FreeBSD 13.1 released installed on a machine and there is NO firewall service running on it, it has two interfaces one with public IP and the other with private IP. I can not ssh into the machine from a public IP apart from the public IP of the same network and I can ssh into the...

I'm fairly new to IPFW but have read the various examples and the manual page carefully. I can't seem to find a way to log a successful connection without logging all subsequent packets. I thought the best way would be using keep-state but that doesn't work the way I intended. With IPFILTER...

Hi All ,
I need to audit the rules and settings of a FreeBSD firewall against best practice ""my first time", the client has sent me a text file .
Is there a software I can use to make this analysis? If not, what is the best process for auditing this FreeBSD firewall?

We are having trouble with finding ways to redirect the public IP address to the jail IP address. We have looked into the rc.conf and jail.conf files but are now sure how we should edit any of these files to achieve this.
We have previously been unsuccessful in editing pf values...
I run a FreeBSD VPS where it's located a webserver with WHMCS inside. (Apache + Nginx)
I would like to do other kind of ad by running a prank on social media where people will get message like "X has been hacked. Click here to download database" or something similar.
What I need?
I need to release an application that accesses the amazon.
With each ping in the URL of the application hosted in amazon the IP changes from time to time.
The local application does not support proxy.
I use freebsd / ipfw.
Example ping return:
app.example.net -> a.a.a.b
