Any help would be wonderful!!
The sudo traceroute -T -O info 45.135.106.143 -p 873 command clearly shows you cannot reach the destination, in fact, your packets seem they cannot reach even the next host, and certainly they cannot go beyond your local network.
Here is the output of a successful traceroute using the command you used. It shows the packets can reach the gateway (192.168.1.1) and also transit the global internet:
sudo traceroute -T -O info 45.135.106.143 -p 873

So, seem like your firewall is on the local network side preventing packets from even reaching your gateway router or else you also have a local host firewall. You can try removing the firewall to test if your connection can be established.

But, this is the command that does not specify the rsync port so it does not test whether the port 873 is open on your host/network firewall. The command you posted that does specify the rsync port does show that the packets leave the network. In your post, both of the commands that specify the rsync port commands fail:
sudo traceroute -T -O info 45.135.106.143 -p 873
and
sudo nping --tcp --traceroute -c 13 -p 873 feed.community.greenbone.net

My apologies, you are right I missed the port. However, when I run it directly from the Firewall using the WAN port I lose traffic halfway through… I need to see if I can do this from a hotspot some how… I can’t figure out why my allow port rule is not working on the firewall then…

You are not losing traffic halfway through. This shows a successful connection same as your command without the port specified. You can see that the final hop is the same in both outputs.

So it is still the port being blocked either directly from the WAN port on the firewall or the KAli Purple box behind the LAN port on the firewall?
You can use the online port checker to see that the port is open on Greenbone’s server. You need to specify a custom port and use 873 as the screenshot shows the port is open and connection is OK:

I guess it’s being blocked due to an outgoing rule on the LAN or WAN side of the firewall or on a host firewall. If you have any security software products on the host such as EDR or even many modern “malware scanners” may block the outgoing rsync port because it may easily be used for data exfiltration.

I will have to check but I don’t think Kali comes native with the firewall enable. I will have to check when I get back. I also will try to disable the apps on the firewall just to make sure.
Sorry, I forgot you were using Kali. You are right Kali doesn’t typically come with a firewall installed or enabled. However, I haven’t used Kali Purple yet so I don’t know for sure.
I will let you know after I look tonight but my assumption is it doesn’t. Kali Purple is basically SOC (Security Operations Center) in a box. Basically it is a Kali installer with all the tools preloaded for an SOC to install on hardware or virtual machine… So far the first thing to to is configure Greenbone.
Yes, I have been meaning to test the Greenbone install on Kali Purple, and seems that there is no built-in firewall and I can connect to the rsync server.
Thanks so much for checking! I just got home. I’ll test the pfsense policies as well.
I finally got the traceroute to work but not the actual rsync…
sudo traceroute -T -O info 45.135.106.143 -p 873
traceroute to 45.135.106.143 (45.135.106.143), 30 hops max, 60 byte packets

2 45.135.106.143 (45.135.106.143) <rst,ack> 0.488 ms 0.475 ms 0.503 ms
I guess this is going to be a baby steps resolution…
