Subject RE: Problem with VM private IP
Date Mon, 24 Sep 2012 10:52:55 GMT
Using firewall and port forwarding rules only  we can access the VM services from the public
network also from the VMs using the Public IPs.
For you  telnet from outside network success but from failed from VM to VM using public IP.
Seems hair pin NAT  got failed ...

Please capture the packets on the telnet server VM to see whether telnet packets are reaching
or not ?

Which version of cloudstack Is it ?

Thanks,
Jayapal

Subject: Problem with VM private IP

Hi everyone,

I have a problem while working with VM private IP. My Cloud system run 2 VMs in advance zone
with private IP is 10.1.1.20 and 10.1.1.21 and VM NAT IP is 192.168.50.160 and 192.168.50.165.
From outside network, I can ping and telnet port 80 to both VMs with public IPs. But from
VM 10.1.1.21, I can't telnet to other VM with its public IP.

For details:
>From VM1: 10.1.1.20 and 192.168.50.160.
ping 192.168.50.165 and ping 10.1.1.21 success telnet 10.1.1.21 80 success telnet 192.168.50.165
80 fail

>From VM2: 10.1.1.21 and 192.168.50.165
ping 192.168.50.160 and ping 10.1.1.20 success telnet 10.1.1.20 success telnet 192.168.50.160
80 fail

And I can't telnet another ports with public IP.

Can you suggest some solutions for me to telnet VM from another VM via public IP.

Thank !
