Dear All
As shown in the picture, from the external application server to the external web server, I test “nmap -Pn 172.24.0.76” and found 80,81,443 ports are blocked. If i call with local ip address 192.168.10.3 with nmap command form external web server, 80,81,443 ports status are open.
Similarly, if i test with nmap -Pn 172.24.0.77 with public ip from the external app server to the internal web server, there are 80,81,443 ports.
All open.
Next, i test the external web server from the internal App Server with nmap -Pn 172.24.0.76 and the ports are 80,81,443.
I see it all open.
Another thing, from the internal application server, ping the internal web server with public ip nmap -Pn 172.24.0.77.
The ports are not open. However, if i test the local ip address of the internal web server 192.168.20.2, with the nmap command.
The ports are open.
So what kind of additional firewall rules do we need to configure in the mikrotik router.
