On the machine where this port needs to be opened, execute the below commands:
If you have an external firewall sitting in between these two machines, you have to follow the instructions/manuals for that firewall.
Typically, using telnet you can determine whether a port on remote host is open or blocked by a firewall by the error message it throws.
For example:
Unable to connect to remote host: No route to host => this type of error message is seen in case of a blocked port
Unable to connect to remote host: Connection timed out => this is seen in case of a closed port

connect-proxy
CONNECT-PROXY(1) General Commands Manual CONNECT-PROXY(1)NAME
connect-proxy -- connect over SOCKS4/5 proxy
SYNOPSIS
connect-proxy [-dnhst45] [-R resolve ] [-p local-port ] [-w secs ] [-H [user@]proxy-server[:port]] ] [-S [user@]socks-server[:port]] ]
[-T proxy-server[:port] ] [-c telnet-proxy-command ] [host] [port]
DESCRIPTION
connect-proxy open connection over SOCKS4/5 proxies
Please, note that any HTTP-Proxy tunnel won't work with content-inspection firewall (unless using SSL).
OPTIONS -H specifies a hostname and port number of the http proxy server to relay. If port is omitted, 80 is used. You can specify this
value in the environment variable HTTP_PROXY and pass the -h option to use it.
-S specifies the hostname and port number of the SOCKS server to relay. Like -H, port number can be omitted and the default is
1080. You can also specify this value pair in the environment variable SOCKS5_SERVER and give the -s option to use it.
-4 specifies SOCKS relaying and indicates protocol version to use. It is valid only when used with '-s' or '-S'. Default is '-5'
(protocol version 5)
-R method to resolve the hostname. Three keywords ("local", "remote", "both") or dot-notation IP address are acceptable. The key-
word "both" means, "Try local first, then remote". If a dot-notation IP address is specified, use this host as nameserver. The
default is "remote" for SOCKS5 or "local" for others. On SOCKS4 protocol, remote resolving method ("remote" and "both") requires
protocol 4a supported server.
-p will forward a local TCP port instead of using the standard input and output.
-P same to '-p' except keep remote session. The program repeats waiting the port with holding remote session without disconnecting.
To connect the remote session, send EOF to stdin or kill the program.
-w timeout in seconds for making connection with TARGET host.
-d used for debug. If you fail to connect, use this and check request to and response from server.
USAGE
To use proxy, this example is for SOCKS5 connection to connect to "host" at port 25 via SOCKS5 server on "firewall" host.
connect-proxy -S firewall host 25
SOCKS5_SERVER=firewall; export SOCKS5_SERVER; connect-proxy -s host 25
For a HTTP-PROXY connection:
connect-proxy -H proxy-server:8080 host 25
HTTP_PROXY=proxy-server:8080; export HTTP_PROXY; connect-proxy -h host 25
To forward a local port, for example to use ssh:
connect-proxy -p 5550 -H proxy-server:8080 host 22 ssh -l user
To use it along ssh transparently:
# file://~/.ssh/config
# not using proxy on lan
Host 192.*
ProxyCommand connect-proxy %h %p
# mandatory to access the internet
Host *
ProxyCommand connect-proxy -H proxyserver:8080 %h %p
Or for all users ( /etc/ssh/ssh_config )
ENVIRONMENT
SOCKS5_USER, SOCKS5_PASSWORD, HTTP_PROXY_USER, HTTP_PROXY_PASSWORD, CONNECT_PASSWORD, LOGNAME, USER
SEE ALSO
ssh (1).
