fire wall on VPS

[microvps]

CSF is good solution. Assuming that should be popular among lots of the end users and providers.

We tried both APF and CSF on my servers. I can make a conclusion that they are both good, there is no big difference between them

And both APF and CSF are easy to be configured too, I should say.

CSF is rather a wrapper program around iptables, iptables do the actual blocking, although csf includes other security features along side.

Yes, you can install a firewall on the main server and use it to protect all VPS on the same machine.

You can try to install eBox as a virtual server. It can be your virtual firewall.
You then configure your other virtual servers' network gateway to this virtual firewall.

Definitely take a look at CSF for a firewall

It's what i usually use and i find it works pretty well

Already you have been told that you can install firewall on your VPS.Here I will recommends you APF or IPtables.
