About Port Forwarding

You can forward one or more TCP or UDP ports on one computer to another so that separate networks can be bridged.

RemotelyAnywhere can provide SSL encryption even if neither the client nor the server supports it. In this case, you can use two installations of RemotelyAnywhere: one to translate the connection from TCP to SSL, the other to translate it back from SSL to TCP.

If you have two RemotelyAnywhere Port Forwarding Servers communicating with each other, you can also utilize the proprietary Compressed SSL (CSSL) protocol instead of using plain SSL. CSSL can also seamlessly compress, uncompress, encrypt, and decrypt your data.

How to Configure Port Forwarding

Access the port forwarding rules in Server Functions > Port Forwarding Config.
Click Create forwarding rule.
Result: The port forwarding properties page is displayed.

Enter the details of your port forwarding rule.

Option	Description
Protocol	Select the protocol type of your incoming and outgoing connection. You can specify SSL, CSSL, or TCP. To translate SSL connections to TCP, and thus behave as an SSL proxy for applications that are not SSL-enabled, set one end to SSL and the other end to TCP.
IP Address	The IP address from which (In) or to which (Out) you want to forward communication.
Port	The port on which the computer is listening for communication (In) or to which it tries to forward data (Out).
IP address filter profile	Select a profile filter to restrict incoming connections to the corresponding port forwarding rule.
Defer	Specify a timeout value for a special condition. When one end of the connection has been closed, but the other is still open, the Port Forwarding Server (PFS) will wait this much time for the open end of the connection to be closed. It will then close the connection itself.
Timeout	This setting lets you specify how long the PFS will hold a connection open with no data going through it in either direction. When the amount of time specified here is reached and the connection is idle, both ends of the connection will be closed gracefully.
Description	Specify a remark associated with the port forwarding item. This will be displayed on the main screen.
Enabled	The status of the port forwarding rule.

Click Apply.

Example: Example 1

Suppose that you are using a laptop with a dialup account, and your email software does not support SSL. Also suppose that your corporate mail server does not support SSL either. If you still want to keep your email secure, you can install RemotelyAnywhere both on your laptop and on the email server, and set up port forwarding on both computers.

On your laptop, you must do the following:

Create a port forwarding rule with the incoming IP address as 127.0.0.1 (the loopback address), the incoming port as 3110, the incoming protocol is TCP. The outgoing IP address or host name would be set to that of your email server, the outgoing port would be set to 3110, and the outgoing protocol would be SSL to enable encryption.
Change your email client's preferences so that the POP3 server is 127.0.0.1 and the port is 3110.

On the mail server, you must create a port forwarding rule with the incoming IP address set to your mail server's Internet IP address, the incoming port set to 3110, and the incoming protocol set to SSL. The outgoing IP address would be the same (the mail server's Internet IP address), the outgoing port would be 110 (the standard POP3 port), and the outgoing protocol would be set to TCP to enable decryption on the mail server.

You must also have to create one additional port forwarding item on both computers for the SMTP protocol that is used to send email as opposed to receiving it. This runs on port 25 by default.

How to View Port Forwarding Status

Access the port forwarding rules in Server Functions > Port Forwarding Status.
Click Refresh to refresh the list.

How to View Active Directory Settings

RemotelyAnywhere provides an Active Directory browser. It lets the user connect to and browse through the various elements in the Windows domain's active directory tree. It provides a useful system information tool.

Access the port forwarding rules in Server Functions > Active Directory.
Click the name of an Active Directory entry to view its details.
Select one of the following options:
- Click Refresh to refresh the list
- Click Parent to go back to the parent directory
- Click Root to return to the root directory of your Active Directory
- Click Back to return to the previous page
