Subject RE: VMs can not access to Internet via Public IP ???
Date Sat, 15 Sep 2012 19:41:26 GMT
Hi Dinh,

You would need to set up port forwarding rules for the guest VMs to enable them send outbound
traffic. In the CS GUI, go to Networks -> click on a network that your VM is associated
with -> View IP addresses -> click on the IP you acquired for the VM -> Configuration
-> click on view all in Port Forwarding -> choose the protocol and define the applicable
port ranges and/or other values, and associate this rule with a VM. In case of ping, use -1
for both the icmp type and code if you want to enable the rule for all code+type combinations.

Subject: VMs can not access to Internet via Public IP ???

I deploy CS model follow as:

1.      MS: 2 NIC card: NIC 1: gw, NIC 2: gw NIC 1 is can connect to Ineternet.

2.      Node : 1 NIC with IP with XCP. Node connect to MS’s NIC 2 via
a switch.

3.      NFS server: 1 NIC with IP and connect to MS and node via a switch.

4.      Public network

5.      Pod ip range:

6.      Storage traffic: 172.15.0/24

7.      Guest range:
I create Zone and VMs OK. But I have a problem. VMs, SSVM, VR, CPVM can not connect to outside
(MS NIC 1 IP, internet) via Public IP.?????  They can connect to machines that belong to
network. I try ssh to SSVM, VR, CPVM and use ping command to or and
tcpdump on Node server but have not any packet send through Node’s NIC.  Can u help me .
Thanks and bestregard.
