Subject Re: recreate iptables rules on hosts
Date Mon, 11 Aug 2014 23:48:20 GMT
I have tried to restart the network with and without the cleanup option and
this doesn't work for me.

With cleanup option the vr is destroyed and recreated and I see entries
made for the virtual router in the host's iptables however I see nothing
else for the other instances.

With cleanup option unchecked I see no changes to the iptables on any hosts.

I tried copying the iptables from my other 4.4 + 6.2 installation (this one
is 4.3 + 6.0.2) where it does not have VM specific rules but I am able to
ssh to my instances, but that did not work.

If I stop iptables I am able to access my instances.  I am ok leaving it
like this but the problem is that every time a new instance is create, the
management server send ipset commands that start it again and then I can't
access any of my instances.

This is supposed to be a basic shared network without security groups.

any ideas what is going on or how to disable iptables permanently?
