Packet Sender Tool

Hello,

I am new to networking and I am trying to play around with a couple of different tools.

I want to send TCP packetz from one machine to another using Packet Sender and capture using wireshark.

However upon filling up the required fields such as Destination Address,Port Number etc.

I am getting an Error Message: Could Not connect.

The Destination Ip address is valid, My port forwarding is also enabled.

I would really appreciate some suggestions.

Thanks in advance.
