I am not sure what is the purpose of this question, nor if you are going to use it in a legal way.
To change a local port to be coming from another IP - this is called tunelling. It is quite simple.
If you want to make this on some local machine then you need to mangle with the TCP/IP. There are multiple ways to achieve that. I would suggest Linux + IPTables + SNAT (Source NAT) which is exactly what you need. You might use google to find how to do a SourceNAT (SNAT) on other platforms and using some specific tools.

Short description of what SNAT might be:
"If a packet is going out from my PC from port 1234 then its source IP should be replaced to IP 5.6.7.8". It would be something like (might be wrong as I am not testing that): "iptables -A MANGLE -p tcp --sport 1234 -j SNAT --from-ip 5.6.7.8"

NAME

       asadmin-list-instances, list-instances - lists all the instances in the server

SYNOPSIS

       list-instances  [--user	admin_user]  [--password  admin_password]  [--host localhost] [--port 4848] [--domain domain_name] [--local=false]
       [--passwordfile filename] [--secure|-s]

       Use the list-instances to list all the instance in the server. The list-instances command can be run both locally and  remotely.   To  list
       remote  instances,  the named administration server must be running on the hostname and port number specified. The user authenticates using
       the password identified for the administration server.

OPTIONS

       --user		       administrative user associated for the instanace.

       --password	       administrative password corresponding to the administrative user.

       --host		       host name of the machine hosting the administrative instance.

       --port		       port number associated with the administrative host.

       --domain 	       name of the domain.

       --local		       determines if the command should delegate the request to administrative instance or run locally.

       --passwordfile	       file containing passwords appropriate for the command (e.g., administrative instance).

       --secure 	       if true, uses SSL/TLS to communicate with the administrative instance.

       Example 1: Using list-instances in local mode

       asadmin> list-instances --domain1 --local
       admin-server running
       server1 running

       Where: the server1 and admin-server instances for the domain1 domain is listed.

       Example 2: Using list-instances in remote mode

       asadmin> list-instances --user admin --passwordfile passwords.txt --host localhost --port 4848
       server1 [mayank:80] running

       Where: the server1 instance associated with the specified user, passwords, host, and  port  number  specified  is  listed  for  the  remote
       machine.
