Iptables of Host machine blocks http traffic to Guest VM's
Hello,
Finally, I have created a template from centos 6.8 ISO with jdk 1.8 installed and a web application hosted. I can now create VM's from this templates and they work fine except one problem. The web applications in guest VMs created from template are only accessible from the host running the VMs. If I access them (web applications) from some other system on the same LAN they are not accessible until I turn off the iptables service on host machine. Is there an ip table rule that I can add to work around this problem not only for the existing VMs but for the VMs I will be creating on this host in the future?
Regards
Adeel

Adeel,
Take a look at the admin guide - http://docs.cloudstack.apache.org/projects/cloudstack-administration/en/4.9/networking_and_traffic.html#egress-fw-rules

I am using KVM as hypervisor and for network configuration I followed the following link
http://docs.cloudstack.apache.org/projects/cloudstack-installation/en/4.6/qig.html
Except that my ip addresses are from 10.0.0.x series. And I do not know about ingress/egress rules and how to configure them.

What type of deployment are you using?
Did you try configuring the ingress/egress rules for the network of the VM
you are creating?

One more finding. Even restarting the iptables service does the trick. Why is that? What can I do to avoid having to restart the iptables service?
