Why doesn't Mikrotik allow traffic from multiple IPs through one physical interface?

Question

Mikrotik

The provider gave me 4 public addresses.
Let's assume this is 1.1.1.1, 2.2.2.2, 3.3.3.3, 4.4.4.4.
All addresses are registered on one physical port. Command
/ip address add address=1.1.1.1/32 interface=ethernet1
/ip address add address=2.2.2.2/32 interface=ethernet1
/ip address add address=3.3.3.3/32 interface=ethernet1
/ip address add address=4.4 .4.4/32 interface=ethernet1 Trying to
ping 1.1.1.1 from the internet. Ping is coming.
I'm trying to ping 2.2.2.2 from the Internet. There is no ping.
I try to ping 3.3.3.3 from the Internet. There is no ping.
I try to ping 4.4.4.4 from the Internet. There is no ping.
I turn off the address 1.1.1.1. I check the ping on 2.2.2.2 - it goes. I include the address 1.1.1.1. I check 1.1.1.1 ping is coming.
I include all IPs. I am overloading the router. There is no ping. I turn off and turn off IP 1.1.1.1. The ping works.
What is the point? Why does ping only work after juggling IP addresses?
I can't find patterns. Now rebooted and everything works. Sometimes I overload and ping only one IP. Firewall turned off. NAT too.
UPDATED:
The provider issued a pool of addresses from its router connected to the switch.
For example:
network 8.8.8.208/29
gateway provider 8.8.8.209
IP 8.8.8.210 Mikrotik first port, provider switch 1 port
IP 8.8.8.211 Mikrotik first port, provider switch 1 port
IP 8.8.8.212 Mikrotik first port, provider switch 1 port
IP 8.8.8.213 The server is connected directly to the provider switch, provider switch 2 port
IP 8.8.8.214 Mikrotik first port, provider switch 1 port
IP 8.8.8.215 Broadcast
8.8.8.210 = GW (192.168.1.1) for local network users.
8.8.8.211 = Linux server (192.168.1.200) on LAN
8.8.8.212 = Linux server (192.168.1.201) on LAN
8.8.8.214 = Linux server (192.168.1.202) on LAN LAN
192.168.1.0/24
Mask / 32 for each specific address was made in order not to affect the IP 8.8.8.213 (which is connected to the server directly bypassing the router).
How to do NAT ONE-TO-ONE?
/ip address add address=8.8.8.208/29 interface=ethernet1
/ip firewall nat add chain=dstnat dst-address=8.8.8.211 action=dst-nat \
to-addresses=192.168.1.200
/ip firewall nat add chain=srcnat src-address=192.168.1.200 action=src-nat \
to -addresses=8.8.8.211
Only if I do this command /ip address add address=8.8.8.208/29 interface=ethernet1
won't my router accept packets for host 8.8.8.213 ?
Or is the provider configured so that packets for IP 8.8.8.213 will only come from the second switch port, and everything else (8.8.8.210, 8.8.8.211, 8.8.8.212, 8.8.8.214) from the first?

Answer 1

Do not use /32 without a clear understanding of what it is and why in this situation.
How exactly did the provider give you 4 public addresses? How does the connection work in general?
And why /32?

Answer 2

I strongly recommend that you read books and articles about how networks work, since you simply do not have enough base, you confuse everything into one mess.
start with this https://habrahabr.ru/post/134892/
you can somehow set up network equipment with copy-paste, and then shout that it does not work
