Re: [Rdo-list] I can't get access to VM instances

Hi Rhys, I suppose so, because these are my iptables rules: iptables -F iptables -t nat -F iptables -P INPUT ACCEPT iptables -P OUTPUT ACCEPT iptables -P FORWARD ACCEPT iptables -A INPUT -d 172.16.58.0/24 -m state --state ESTABLISHED,RELATED -j ACCEPT iptables -A INPUT -d 172.16.58.0/24 -p tcp --dport ssh -j ACCEPT iptables -A INPUT -d 172.16.58.0/24 -p tcp --dport www -j ACCEPT iptables -A INPUT -d 172.16.58.0/24 -p tcp --dport pptp -j ACCEPT iptables -A INPUT -d 172.16.58.0/24 -p tcp --sport domain -j ACCEPT iptables -A INPUT -d 172.16.58.0/24 -p tcp --dport domain -j ACCEPT iptables -A INPUT -d 172.16.58.0/24 -p udp --sport domain -j ACCEPT iptables -A INPUT -d 172.16.58.0/24 -p udp --dport domain -j ACCEPT iptables -A INPUT -d 172.16.58.0/24 -p gre -j ACCEPT iptables -A INPUT -d 172.16.58.0/24 -p icmp -j ACCEPT iptables -A INPUT -d 172.16.58.0/24 -j DROP iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE service iptables save Firstly, do you think I planned the network organisation well? Do you have other suggestion (best practices) with 2 interfaces? 2015-02-20 18:30 GMT+01:00 Rhys Oxenham <roxenham(a)redhat.com&gt;: > Hi Pasquale, > > Did you modify your security group rules to allow ICMP and/or 22:tcp > access? > > Many thanks > Rhys > > > On 20 Feb 2015, at 17:11, Pasquale Salza <pasquale.salza(a)gmail.com&gt; > wrote: > > > > Hi there, I have a lot of problems with RDO/OpenStack configuration. > Firstly, I need to describe my network situation. > > > > I have 7 machine, each of them with 2 NIC.
