You can do a tunnel on ssh as a port forwarder, where it listens somewhere for the RDP client tcp connection and forwards it to the target desktop port 3389 (or whatever port you reconfigure to. For instance you can ssh localhost on a firewall host and make tcp port 3389 listen there and forward connections to the windows box port 3389.

If the ssh encryption is not a concern, there is a program tcpRelay.c that can listen of be an inetd child and forward to any given port, even allowing configuration of specific host access permissions and different destinations, as a general firewall tcp proxy.

ssh-socks5-proxy-connect(1)					   User Commands				       ssh-socks5-proxy-connect(1)

NAME
ssh-socks5-proxy-connect - Secure Shell proxy for SOCKS5 SYNOPSIS
/usr/lib/ssh/ssh-socks5-proxy-connect [-h socks5_proxy_host] [-p socks5_proxy_port] connect_host connect_port DESCRIPTION
A proxy command for ssh(1) that uses SOCKS5 (RFC 1928). Typical use is where connections external to a network are only allowed via a socks gateway server. This proxy command does not provide any of the SOCKS5 authentication mechanisms defined in RFC 1928. Only anonymous connections are possi- ble. OPTIONS
The following options are supported: -h socks5_proxy_host Specifies the proxy web server through which to connect. Overrides the SOCKS5_SERVER environment variable. -p socks5_proxy_port Specifies the port on which the proxy web server runs. If not specified, port 80 is assumed. Overrides the SOCKS5_PORT environment variable. OPERANDS
The following operands are supported: socks5_proxy_host The host name or IP address (IPv4 or IPv6) of the proxy. socks5_proxy_port The numeric port number to connect to on socks5_proxy_host. connect_host The name of the remote host to which the socks gateway is to connect you. connect_port The numeric port number of the socks gateway to connect you to on connect_host. EXAMPLES
The recommended way to use a proxy connection command is to configure the ProxyCommand in ssh_config(4) (see Example 1 and Example 2). Example 3 shows how the proxy command can be specified on the command line when running ssh(1). Example 1 Setting the proxy from the environment The following example uses ssh-socks5-proxy-connect in ssh_config(4) when the proxy is set from the environment: Host playtime.foo.com ProxyCommand /usr/lib/ssh/ssh-socks5-proxy-connect playtime.foo.com 22 Example 2 Overriding proxy environment variables The following example uses ssh-socks5-proxy-connect in ssh_config(4) to override (or if not set) proxy environment variables: Host playtime.foo.com ProxyCommand /usr/lib/ssh/ssh-socks5-proxy-connect -h socks-gw -p 1080 playtime.foo.com 22 Example 3 Using the command line The following example uses ssh-socks5-proxy-connect from the ssh(1) command line: example$ ssh -o'ProxyCommand=/usr/lib/ssh/ssh-socks5-proxy-connect -h socks-gw -p 1080 playtime.foo.com 22' playtime.foo.com ENVIRONMENT VARIABLES
SOCKS5_SERVER Takes socks5_proxy_host operand to specify the default proxy host. SOCKS5_PORT Takes socks5_proxy_port operand to specify the default proxy port. EXIT STATUS
The following exit values are returned: 0 Successful completion. 1 An error occurred. ATTRIBUTES
