Hello Jagdish
Thanks for reaching out to help me. I disabled both firewalld.service and iptables.service after stacking. I am not sure how sysctl with kernel plays a role here - would you please elaborate Thanks In Advance Siva ________________________________ From: Jagdish Goswami <jagd...@zymr.com> Sent: 22 September 2017 12:02 To: Sivavakeesar S Dr (Elec Electronic Eng) Cc: openstack Subject: Re: [Openstack] Ping and SSH not working with VM Hi, Pelase check iptables setting.And also check syctl settings.

I successfully created a network and attached a VM to my private network. I also assigned a floating IP to the VM that has been attached to my network. I added a Security Group that literally allows all ICMP, tcp and udp traffic in either direction. But when I tried with SSH and ping, I am getting the following errors: ssh -i uoskeypair.pem cirros@10.5.22.113<mailto:cirros@10.5.22.113> ssh: connect to host 10.5.22.113 port 22: No route to host ping 10.5.22.113 PING 10.5.22.113 (10.5.22.113) 56(84) bytes of data.
