Port forwarding on Mikrotik?

Question

Computer networks

Hello everyone
I'm trying to forward the port on Mikrotik towards the server. I did everything according to the manuals
But something doesn't work
Where am I the fool?

Filter Rules

NAT

nmap

/ip firewall export

/ip firewall filter
add action=accept chain=input comment="default configuration" connection-state=established,related

Answer 1

Unload /ip firewall export
Without it, it is not clear what and how. The screenshots do not show all the information.

Answer 2

In Filter, add a rule allowing forward to 192.168.88.110:444

Answer 3

And who will specify the incoming interface?

Answer 4

Below, working configuration for firewall/NAT with open ports for L2TP IPSec, web interface and port forwarding 444 to ip 192.168.88.110

/ip firewall nat
add action=masquerade chain=srcnat comment="masquerade" ipsec-policy=out,none out-interface-list=WAN
add action=netmap chain=dstnat dst-port=444 in-interface=ether1 protocol=tcp to-addresses=192.168.88.110 to-ports=44
/ip firewall filter
add action=accept chain=input comment="ALLOW ESTABLISHED" connection-state=established
add action=accept chain=input comment="ALLOW RELATED" connection-state=related
add action=drop chain=input comment="DROP INVALID" connection-state=invalid
add action=accept chain=input comment="ALLOW ICMP" protocol=icmp
add action=accept chain=input comment="ALLOW WINBOX" dst-port=8291 protocol=tcp
add action=accept chain=input comment="ALLOW L2TP IPSEC" dst-port=500,1701,4500 in-interface=ether1 protocol=udp
add action=accept chain=forward comment="ALLOW L2TP IPSEC" protocol=ipsec-esp
add action=accept chain=input comment="ALLOW WEB-INTERFACE" dst-port=80 protocol=tcp
add action=drop chain=input comment="DROP ALL INPUT"
add action=accept chain=forward comment="ALLOW ESTABLISHED" connection-state=established
add action=accept chain=forward comment="ALLOW RELATED" connection-state=related
add action=drop chain=forward comment="DROP INVALID" connection-state=invalid
add action=accept chain=forward comment="ALLOW ICMP" protocol=icmp
add action=accept chain=forward comment="ALLOW REDIRECT TO RDP" dst-port=444 protocol=tcp
add action=accept chain=forward comment="ALLOW INTERNET FROM LOCAL" out-interface=ether1 src-address=192.168.88.0/24
add action=drop chain=forward comment="DROP ALL FORWARD"

Answer 5

The screenshot shows that the packets go through the nata rule, maybe the problem is still in the server?

Answer 6

at the server the gateway is registered?
