Checking the firewall configuration and release port 3050 to access the firebird through vpn.
Currently through ssh I see the door open with the command nmap localhost, but on the local network only ping the server ip and the command nmap 220.127.116.11 port 3050 does not appear.

Note: To perform the configuration I sending a user (VPN) to connect to the server.
