Random Lost Packets When Pinging Through Different Subnet

[rohanr...@gmail.com]

I set up several VMs via Vagrant.

    # Machine

    config.vm.box = "ubuntu/xenial64"

    config.vm.provider "virtualbox" do |vb|

        vb.memory = "2048"

        vb.cpus = "2"

    end

    # Networking

    config.vm.hostname = "domain.com"

    config.vm.network "public_network", ip: "10.10.2.29", bridge: "p1p1"

    # default router

    config.vm.provision "shell",

    run: "always",

    inline: "route add default gw 10.10.2.1"

Now the vagrants can ping each other without packet loss because they are on the same subnet, but when its going through the switch from my machine(10.10.13.XX) there is about 3-10% packet loss. Weirdly enough I can start a screen instance and ping the default gateway continuously so that the loss is negated. I am not a network administrator so I am not sure if there is anything I can do or if I missed something, can someone help?

Thanks!

hello

Can you do vagrant halt, then turn the VM on using the Virtualbox Gui and try the pings from inside?

I don't think this is a Vagrant issue..

From the VM, whats the output of route -n

other option is from virtualbox gui, power the VM off, and check settings of the 2nd network card and test different network cards

perhaps there is one that runs better.

Hi,

I am afraid I have limited access to the Ubuntu GUI. Here is what you asked for.

ubuntu@xxx:~$ route -n

Kernel IP routing table

Destination     Gateway         Genmask         Flags Metric Ref    Use Iface

Hello

Virtualbox gui

If this runs in your computer, is opening Virtualbox.
