ACS 4.4.1 XenServer 6.2 - VMs lost connection in "Isolated" network
Hi All,
I have total of about 5 VMs on "Isolated" network, but they lost
connection to outside world. I am able to ping the VR but can't ping to
outside world. If I log in to VR, am able to ping anywhere outside or
inside network.
out of the 5 VMs, 3 machines never loose connection, the two VMs that do
loose connection are windows machines. To get the connection again, I
have to restart VR. Any ideas?
I want to mentioned that, I have three other "Isolated" networks in the
same zone. I do not have problems with other "Isolated" networks.
I do need help!
Thanks,
Motty

Hi, I've had the same issue but it appear only in Isolated Network inside
VPC.
Also ACL and port forwarding applied to that Internal Network stops
working...

Hi Jayapal,
I was able to "restart Network" clean, to rebuilt the VR. I have not had
those issues in the last 10hrs. I can almost say that fixed my issue but
not certain.
Thanks,

HI Motty,
First make sure there are no issue in the VM like ip addr, route, firewall etc.
Second When you send traffic from the VM, capture the it in each place to figure where exactly the traffic is blocking.
Is it reached to hypervisor, router etc ? This way you can find who is culprit.
Thanks,
Jayapal

Check routes on the guests that are having trouble. You should verify if the public traffic from these guests is reaching the router.
