It sounds like he set up a deny-all-except configuration, with his IP as the only trusted IP. In which case, if his IP changes, it will effectively lock him out. If you can get to WHM, then you can disable CSF in Plugins. Otherwise, you'll need to ask your host to disable it for you.
Have your host, or if you just blocked your IP ssh into another server then into your own, run csf -x to disable it and then iptables --flush. or you can run 'csf -a YOUR IP ADDRESS' to whitelist and begin tuning it to your liking. Just a tip on VPS servers, be sure to turn SAFECHAINUPDATE on. I won't go into details but it will ensure you don't run into issues down the line. Hope this helps!
