Description Mark McLoughlin 2011-08-30 03:05:42 EDT
Currently you need to disable iptables in order to get nova networking

The basic problem is that Nova's rules were written to work on Ubuntu where there are no iptables rules by default and all packets are accepted. The rules need to be adapted to work with Fedora's reject rules
Comment 1 Mark McLoughlin 2011-09-01 15:09:00 EDT
Some progress here. This is enough to get things working for me:

iptables -t filter -A nova-network-INPUT -i br0 -p udp -m udp --dport 67 -j ACCEPT
Comment 2 Mark McLoughlin 2011-09-03 09:52:21 EDT
Okay, I've built this:

* Sat Sep  3 2011 Mark McLoughlin <markmc@redhat.com> - 2011.3-0.7.d4
- Add iptables rules to allow requests to dnsmasq (#734347)

It looks like we also need ACCEPT rules for the meta-data service too, though
Comment 3 Mark McLoughlin 2011-09-05 03:08:05 EDT
Okay, added a rule for that too:

* Mon Sep  5 2011 Mark McLoughlin <markmc@redhat.com> - 2011.3-0.8.d4
- Add iptables rule to allow EC2 metadata requests (#734347)
