snf-network Setup

~~~~~~~~~~~~~~~~~

The following apply to ``ganeti`` nodes.

Install the corresponding package:

.. code-block:: console

   # apt-get install nfqueue-bindings-python=0.3+physindev-1

   # apt-get install snf-network

   # apt-get install nfdhcpd

In `/etc/snf-network/default` add:

.. code-block:: console

   MAC_MASK = ff:ff:f0:00:00:00

Edit `/etc/nfdhcpd/nfdhcpd.conf` to your preferances (DNS, IPv6) and add the

following iptables rules:

.. code-block:: console

    # iptables -t mangle -A PREROUTING -i br+ -p udp -m udp --dport 67 -j NFQUEUE --queue-num 42

    # iptables -t mangle -A PREROUTING -i tap+ -p udp -m udp --dport 67 -j NFQUEUE --queue-num 42

    # iptables -t mangle -A PREROUTING -i prv+ -p udp -m udp --dport 67 -j NFQUEUE --queue-num 42

    # ip6tables -t mangle -A PREROUTING -i br+ -p ipv6-icmp -m icmp6 --icmpv6-type 133 -j NFQUEUE --queue-num 43

    # ip6tables -t mangle -A PREROUTING -i br+ -p ipv6-icmp -m icmp6 --icmpv6-type 135 -j NFQUEUE --queue-num 44

In router node in case you have a NAT setup run:

.. code-block:: console

    # iptables -t nat -A POSTROUTING -s 10.0.1.0/24 -j MASQUERADE

    # ip addr add 10.0.1.1/24 dev eth1

Test your Setup:

Create a VM inside the public network via UI or Ganeti and see if it has internet connectivity.
