I am looking for a system/Program/solution which allow to replace a proxy. The solution allow to edit source IP address before it reach destination, meaning to say, it allows to replace Proxy. I also explore on firewall option, but I am not familiar with firewall, is any firewall allows to map a traffic to an IP address & port before it reach destination, and second request to second IP address & port.
If you know about any solution, please kindly advice. Thanks in advances.
