Google Cloud DNS or Firewall issue [on hold]

We are looking for assistance related to our Magento(Bitnami) Website which is access able through https:// but we can’t access it with www. or http://. Bitnami is using tcp port 81 for http and tcp port 443 for https://.

When we tried to test our website through dnschecker it load with A record but with Cname nothing come up.

I personally think there are some issues with firewall setting.

Windows Server 2016 – Defender Firewall is not blockling inbound UDP packets to application?

Good evening!

The problem: I have a Windows Server 2016 machine with Windows Defender Firewall enabled, I am trying to block inbound UDP packets to a custom network application.

What I’ve tried: I deleted every single rule under Inbound Rules tab tab in Advanced Security but yet the inbound packets (from external network) are still able to reach the application? enter image description here

Firewall cluster Active/Active

I want to make a firewall cluster with load balance and High Availability. I thought to use Proxmox for the cluster and make 2 nodes for the load balance and 2 more for the HA.

The problem is, how can I make the load balance?

I thought make an LACP or some tecnique that can balance the entered traffic on the switch previus to the nodes. But i’m not sure that’s possible.

Do you know if anybody have ever try something like that?

Thanks, and sorry for my english

Separation of devices for VPN / Firewall

Our company has two separate firewall devices from different vendors (Checkpoint / Cisco) for firewall and VPN access. We’re currently evaluating the possibility of migrating to a newer, clustered solution (2 new devices) from a single vendor where both VPN and firewall services will be hosted.

Any thoughts/ideas on what the pros and cons on this?

I’ve read a few articles which state that it’s a good idea to keep them separated due to potential performance penalty, but i really don’t thing that this is going to be an issue (based on the sizing we’ve already made).

Your input would be greatly appreciated.

Gufw Firewall Keeps Turning Off When I Add App Profile

I have the Gufw firewall, I added the following file into my /etc/ufw/applications.d folder called httpd. The file contains this data

[HTTPD] title=httpd description=httpd is apart of XAMPP and is needed to allow mobile devices and virtual machines to connect to your XAMPP server. ports=80 

I also have XAMPP installed. XAMPP is a LAMPP stack server that allows me to create server side websites on my computer and test them out. I want to add this as an app profile to my firewall so I can test my websites out on my phone and tablet which are connected to the same network. Before I added the httpd app profile to the firewall I was unable to connect to my localhost server on my mobile devices when the firewall was on. With the httpd profile I am able to connect to my localhost server on my mobile devices but my firewall keeps turning itself off. How I I know this is when I close Gufw and relaunch it, it shows it is turned off.

I would to have it on at all times and allow my XAMPP server to be accessible on my local network for mobiles devices to connect to.

Any help will be most appreciated.

PF Firewall : Every time I use `pfctl`, I get errors about ALTQ support

I have a slightly elaborate firewall setup where my server usually has between 400 and 800 ip addresses firewalled. It switches back and forth between two different pf tables. Every day it rebuilds the firewall list in the new table and flushes the old one. It does this all via script and it works very well.

But the problem is this ALTQ error. Every time you use pfctl for anything, the first thing it does is output two error lines:

No ALTQ support in kernel ALTQ related functions disabled 

Problem is my script runs pfctl hundreds of times per day. The error log for my script is growing WAY too fast.

Is there any way to suppress these error messages? pfctl does have a -q flag but that’s only for ignoring non-error output. Is there a way I can more fully disable ALTQ in the config file so it won’t even try to use it?

Note that I don’t know what ALTQ is, but I know I don’t need it. My firewall works perfectly aside from the log flood.
