KVM Guest not reachable when iptables service is started

Solution Verified - Updated -

Issue

  • We have installed one RHEL 6 Server with KVM virtualization and one RHEL 6 Guest.

    When the iptables service is stopped everything works fine, if we start the iptables service the guest is not reachable from the network, only from the KVM host.

Environment

  • Red Hat Enterprise Linux 6.2
