If done correctly, those may only be open from the internet, but not from the local network. While SSH may only be available from your local network - or maybe only by the fixed IP of your PC. Other services may only be reachable, when coming from the correct VLAN (assuming you did segment your home network). Maybe your server can only access the internet, but not to the home network, so that an attacker has a harder time spreading into your home network (note: that's only really meaningful, if it's not a software firewall on that same server...)
Instead of thinking with layers, you should use think of Swiss cheese. Each slice of cheese has some holes - think of weaknesses in the defense (or intentional holes as you need a way to connect to the target legitimately). Putting several slices back to back (in random order and orientation) means that the way to penetrate all layers is not a simple straight way, but that you need to work around each layer.
They're pronounced differently (although there's a difference between British English and American English but for these that difference is quite consistent and you just omit the r):
One reason why I cannot spell,
Although I learned the rules quite well
Is that some words like coup and through
Sound just like threw and flue and Who;
When oo is never spelled the same,
The duice becomes a guessing game;
And then I ponder over though,
Is it spelled so, or throw, or beau,
And bough is never bow, it's bow,
I mean the bow that sounds like plow,
And not the bow that sounds like row -
The row that is pronounced like roe.
I wonder, too, why rough and tough,
That sound the same as gruff and muff,
Are spelled like bough and though, for they
Are both pronounced a different way.
And why can't I spell trough and cough
The same as I do scoff and golf?
Why isn't drought spelled just like route,
or doubt or pout or sauerkraut?
When words all sound so much the same
To change the spelling seems a shame.
There is no sense - see sound like cents -
in making such a difference
Between the sight and sound of words;
Each spelling rule that undergirds
The way a word should look will fail
And often prove to no avail
Because exceptions will negate
The truth of what the rule may state;
So though I try, I still despair
And moan and mutter "It's not fair
That I'm held up to ridicule
And made to look like such a fool
When it's the spelling that's at fault.
Let's call this nonsense to a halt."
IPoAC has been successfully implemented, but for only nine packets of data, with a packet loss ratio of 55% (due to operator error), and a response time ranging from 3,000 seconds (50 min) to over 6,000 seconds (100 min). Thus, this technology suffers from extremely high latency.
On 28 April 2001, IPoAC was implemented by the Bergen Linux user group, under the name CPIP (for Carrier Pigeon Internet Protocol). They sent nine packets over a distance of approximately 5 km (3 mi), each carried by an individual pigeon and containing one ping (ICMP echo request), and received four responses.

When the English tongue we speak.
Why is break not rhymed with freak?
Will you tell me why it's true
We say sew but likewise few?
And the maker of the verse,
Cannot rhyme his horse with worse?
Beard is not the same as heard
Cord is different from word.
Cow is cow but low is low
Shoe is never rhymed with foe.
Think of hose, dose,and lose
And think of goose and yet with choose
Think of comb, tomb and bomb,
Doll and roll or home and some.
Since pay is rhymed with say
Why not paid with said I pray?
Think of blood, food and good.
Mould is not pronounced like could.
Wherefore done, but gone and lone -
Is there any reason known?
To sum up all, it seems to me
Sound and letters don't agree.
Instructions unclear, now I'm using the Windows terminal to launch Ubuntu and also have it running in Hyper-V. How does that help me if my windows is out of support? /s
I'm currently experimenting if I can convert my stack to rootless podman.
I found in my notes, that
Could this be your problem?
