Duplicate packets with ping on guest OS(Linux)

[iamdaboss]

Hi,

I am getting lot of duplicate packets when i ping to an IP (router, host system or an internet server) from my guest OS.

Any pointers with this regard would be greatly helpful.

I have the following configuration:

VMware Workstation 6.0.0 build-45731

Host OS: Windows XP SP2 (32bit)

Guest OS: Fedora Core 6 - 32bit (Zod - Kernel ver: 2.6.18-1.2798.fc6)

I have bridged VMnet0 to the 'Wireless Connection' on the Host OS.

In our case was the issue re-solved after correcting the Load Balancing Setting on the vswitch.

I had "Route based on IP Hash" and changed this to "Route based on originating virtual Port"

This is solution for ESXi ??

I have this (DUP!) problem on linux host with VmWare Workstation 17
