<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We are having our test topology running multiple VMs on a server.<o:p></o:p></p>
<p class="MsoNormal">The guest VMs are linux based and the host is based on RHEL 6.4.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The eth interface of VMs are interconnected via ‘intnet’ NIC settings.<o:p></o:p></p>
<p class="MsoNormal">The VMs are using 127/8 IP addresses to communicate with each other.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We are currently using VirtualBoX 3.1.8 and everything works fine.<o:p></o:p></p>
<p class="MsoNormal">But when we upgrade to latest VirtualBoX 5.0.10, we observe that the 127/8 IP addresses are being blocked and it does not reach the VM interfaces.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Based on our testing, it looks like this behaviour is seen from VirtualBox 3.2.0 onwards.<o:p></o:p></p>
<p class="MsoNormal">Can you please suggest if there is a way to get these IP address to be allowed?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Best Regards<o:p></o:p></p>
