Port forwarding, also known as port mapping, enables machines on private networks to communicate with other machines, both private and public computers, over the internet.
Port forwarding for computers is possible by constructing a map between a router’s IP address of a public WAN and that of a private LAN for a device over the private network.
MySQL port forward can be described as the approach used for accessing the Platon Webhosting’s database from a remote location with the help of a SQL client. This method is commonly used when one needs to run MySQL commands or create apps remotely from their server.
MySQL’s port, 3306, isn’t open since it isn’t secured. MySQL port forwarding is possible in Windows and GNU/Linux operating systems.
Secure Shell:
Secure Shell is a secure variation of telnet that is often used in networking. Widely known as SSH. It enables one to enter the shell of a remote server without jeopardizing its security.
Also, it is a protocol for encrypting client-server interactions, also called SSH port forwarding. SSH port forwarding allows the connection to a MySQL server through a firewall even if the MySQL server port has been blocked.
Every communication in a telnet session, which includes the username and password, is sent in plain text, making it possible for anybody with enough resources to sneak within a session and access the password, as well as other kinds of sensitive data.
Session hijacking, in which a hostile user takes control of someone’s session after being accepted for it, is also possible with these kinds of sessions.
Thus, SSH is used to protect against these kinds of issues.
All communications between a MySQL client port and the MySQL server are sent in text, except for the passwords. This implies that if some unauthenticated person comes in between the server and the client, they will have complete access to every data sent.
Encrypting interactions between the MySQL server and the GUI client is essential for safeguarding the data.
Set up
An SSH login account is required for performing SSH port forwarding between a MySQL client application and the MySQL server.
This account must be placed on the MySQL server itself or, in other cases, on a server that is remotely accessible through SSH and can access the MySQL server.
- On the Task Panel, select “Add connection.”
- Enter the properties of MySQL
For instance, port 3306 on the client machine is forwarding to the remote server. Change the source port settings to any value higher than 1024 if the port is already in use.
In case the remote SSH host is on another machine, add the MySQL server’s IP address instead of the current value, i.e., 127.0.0.13
3. Set up the connection
MySQL port is the remote port that would be forwarded to the local port added previously.
4. Click “OK” to save the new settings.
5. Select the newly built connection for connecting to the remote MySQL server.
On the client system, SSH would listen on a specific port, encrypting the received data and sending it to the remote SSH host. The data would be decrypted and forwarded to the MySQL server via the remote SSH host.

Troubleshooting
A PuTTy security alert would most likely appear in case the SSH shell has never been used previously with this server.
For updating the registry keys for the register, select Yes and try again only after the timeout has expired.
If the SQL warning “Connection lost during query” appears, it signifies that TCP networking is disabled in mine. cnf.
Thus, the MySQL server isn’t listening on any TCP/IP ports. In case every process requiring the connection to MySQLd to run on the same host, this could be a security benefit.
All communications with MySQLd should be done over Unix sockets or named pipes. The MySQL database is exceptionally safe, yet one can access it only through the SSH terminal command line rather than TCP/IP.
