Not able to ping freebsd server from my outside world.

Hello All,

I am new to this FreeBSD and facing some issues.

I have installed FreeBSD in cloud environment using the qcow. After installation I am able to ping all my Linux servers from FreeBSD but however reverse in not possible.

When I try to ping FreeBSD from Linux machines, it shows request time out.

Not able to understand what's the issue. Please help.
FreeBSD version - FreeBSD-10.2-RELEASE-i386
Cloud Provider - CloudBand
Did you enable a firewall? What IP addresses are the other Linux machines, are they in the same subnet?
