TFTP timeout while bootstraping nodes (Mirantis Openstack) - openstack

I have a strange issue with TFTP server. While I'm trying to boot my bare-metal Dell R710 to provision new roles to Mirantis Openstack I'm getting:
CLIENT MAC ADDR: ....
CLIENT IP: ...
GATEWAY IP: ...
PXE-E32: TFTP open timeout
But the most strange thing that server will boot successfully after some time (in a few hours).
We are using integrated NICs - Broadcom NetXtream II cards
Please find below tcpdump from tftp/dhcp server (fuel master):
[root#fuel2 ~]# sudo tcpdump ether host d0:67:xx:xx:xx:xx

Issue was solved. Looks like we have a wds service in our network that is listening this subnet as well.

https and http working on local network but only http working outside local network

I'm developing a website. Once when I had Windows 10 + XAMPP + Cloudflare-flexible-ssl I could access my website from outside local network with the lock icon appearing in the browsers and https working like a charm (dispite this solution not being secure between my home-server and cloudflare's end). Now I'm using Ubuntu 20.04 + NGINX + self-made ssl certificate with certbot. It is working like a charm from local network but when I try to access my domain from outside my local network I end up with HTTP working fine but HTTPS stuck with ERR_CONNECTION_TIME_OUT or ERR_CONNECTION_REFUSED, mostly after an page loading that takes very long and never ends.

MY MODEM(NOKIA G-240W-G) CONFIG FOR PORT FOWARDING
enter image description here
What I have done:
Tryed disabling UFW (Ubuntu firewall) but still not working outside local network.
Called my ISP over 10 times. They always say it must be a local network problem. They swear all ports are opened and free to use it.
I'm thinking to fall back to Cloudflare`s flexible ssl and work all trafic upon port 80 or pay for premium internet access or something...

I uploaded my app to an remote VPS exactly the way it was setted on my local network and everything just worked fine. So the problem was my ISP blocking the ports...

Puzzled about the `telnet localhost` and `telnet 0.0.0.0`

I wrote a simple GO program which listens to 0.0.0.0:9999 and 127.0.0.1:9999:
func main() {
go bind("0.0.0.0:9999", "111 ")
go func() {
time.Sleep(2 * time.Second)
bind("127.0.0.1:9999", "222 ")
}()
time.Sleep(time.Hour)
}
func bind(address string, content string) {
fmt.Println("-------------", address, "-----------------")
listener, err := net.Listen("tcp", address)
if err != nil {
panic(err)
return
}
fmt.Println(listener.Addr().String())
conn, _ := listener.Accept()
for {
_, err := conn.Write([]byte(content))
if err != nil {
panic(err)
}
time.Sleep(1 * time.Second)
}
}
The meaning of the code:
It binds two addresses, and gives different responses to the clients of them
binding "0.0.0.0:9999": will send "111 " repeat to client
binding "127.0.0.1:9999": will send "222 " repeat to client
And then I use telnet to try different addresses, and the responses are:
telnet 127.0.0.1 9999: 222 (OK)
telnet localhost 9999: 111 (WHY?!)
telnet 0.0.0.0 9999: 222 (WHY?!)
telnet <my-internal-ip> 9999: 111 (OK)
I'm quite confused about some of them:
telnet localhost 9999: 111 (WHY?!)
localhost should point to 127.0.0.1, so I think it's same to telnet 127.0.0.1 9999 and the response should be 222, but the actual one is 111
telnet 0.0.0.0 9999: 222 (WHY?!)
I think 0.0.0.0 is not same to 127.0.0.1, I expect to get response of 111, but get 222
I also have a demo project: https://github.com/golang-demos/go-bind-0.0.0.0-127.0.0.1-demo
Update: My os is OSX

Both localhost and 0.0.0.0 are resolved to 127.0.0.1 by the OS
$ ping 0.0.0.0
PING 0.0.0.0 (127.0.0.1) 56(84) bytes of data.
64 bytes from 127.0.0.1: icmp_seq=1 ttl=64 time=0.024 ms
$ping localhost
PING localhost (127.0.0.1) 56(84) bytes of data.
64 bytes from localhost (127.0.0.1): icmp_seq=1 ttl=64 time=0.035 ms`
localhost could resolve to something else depending on /etc/hosts file.
An excellent explanation for Linux ping 0.0.0.0 behavior is here.

ip addressing for Nth computers

the question is, calculate these information:
"ip subnet zero, first ip, last ip, broadcast, ip subnet mask"
for a Class B IP (172.16.0.0/16) for X number of PCs, for example, for 27811 computers...

Address: 172.16.0.0 10101100.00010000 .00000000.00000000
Netmask: 255.255.0.0 = 16 11111111.11111111 .00000000.00000000
Wildcard: 0.0.255.255 00000000.00000000 .11111111.11111111
=>
Network: 172.16.0.0/16 10101100.00010000 .00000000.00000000 (Class B)
Broadcast: 172.16.255.255 10101100.00010000 .11111111.11111111
HostMin: 172.16.0.1 10101100.00010000 .00000000.00000001
HostMax: 172.16.108.163 10101100.00010000 .11111111.11111110
Hosts/Net: 27811 (Private Internet)
For a Class B IP address the first 16 digits should be static(they will never change). The remaining 16 digits keep changing...
So for ur problem.. the IP addresses go like this...
172.16.0.1 ..... 172.16.0.255
172.16.1.0 ..... 172.16.1.255
.
.
.
172.16.107.0 ..... 172.16.107.255
172.16.108.0 ..... 172.16.108.163 ---> This will count to 27811 hosts
