Can't send TCP Packages from one VM to another

As the Title says I'm not able to send TCP Packages from on of my Virtual Machines to another VM. UDP on the other hand works just fine.

What I can also see from the GUI is that Package Sender tries to send e.g. from port 3903423209 which is clearly not correct since the tcp port range is "only" from 0-65535.

Has someone also encountered this Problem?

  • Have you tried setting your network connections to "bridged" adapter?

    Also, Packet Sender attempts to bind to "any". If you have more than 1 network adapter, it is basically random which Packet Sender will use. The workaround is to disable network adapters you are not using.

  • What OSes are you using? I have not heard of this problem. It's usually all-or-nothing.

  • I have a Windows Host with VMware. I want to send tcp packages from a Ubuntu 16.04 VM to a QNX VM. I can send tcp packages with other tools like sendip.
    What I've seen in the Wireshark trace is that my Ubuntu Machine asks what i think is your Proxy from the company about the IP address.
    HTTP 176 CONNECT 192.168.188.128:1800 HTTP/1.1
    and this does not work.
    HTTP 590 HTTP/1.1 407 Proxy Authentication Required (text/html)
    This is also not what i want.
    I just want to send TCP Messages between these VM which are in the same Subnet.
