Cant access OpenStack instance from other devices

I have done a DevStack installation of OpenStack on a server.

I have added ICMP and SSH rules to the security group. And have made instances on it.

I can ssh and ping these instances from the host machine.

Now the problem is that I'm unable to ssh or even ping my instances from other machines on this network. And the fun part is that these instances can ssh/ping other machines and even ping my other server and ssh VM's on this server.

I hope I made sense but if you have more to ask, please let me know

Solution

  • Doing this worked out fine for me

    echo 1 > /proc/sys/net/ipv4/ip_forward

    iptables -t nat -A POSTROUTING -o eno1 -j MASQUERADE

    echo 1 > /proc/sys/net/ipv4/conf/eno1/proxy_arp
