So that's likely not a firewall issue on your mysql server but somewhere between mysql-client and mysql-server is a component that does packet filtering. (Or possibly on your mysql-client machine, but highly unlikely. Just make sure you have no firewall rules configured on your client(iptables -L -v -n)).

So you must figure out which devices are between the mysql-server and client and doing the filtering.

I just checked the client and there are no firewall rules configured there.
My client is hosted on AWS and I have setup the security groups to allow all inbound and outbound traffic on all ports for now

I am not too familiar with Rackspace so perhaps they have something similar to Security groups that may be blocking the connections
