You will have to flush your iptables (iptables -F or apf -f)

You have misconfigured APF, such as setting the wrong interface.

I think you may not able login to your server as all ports are blocked.

So you need to ask you datacenter to hookup a console port and flush the iptables rules.

Once they do that you should be able to ssh and at that point you can carefully create rules using iptables and also make sure the /etc/apf/conf.apf file have all required ports i.e 22 (or a non-standard port).
