Ive got VPS running on an Open VZ virtualisation instance. Unfortunately im having a lot of trouble getting a firewall up and running. Ive tried my usual UFW and shorewall, but neither of them would start up.
The company that runs the vps suggested i use csf here but that again wouldnt start up. I then tried modifying IPTables directly, but now that wont start up either. Reading through similar, it looks like its open VZ thats giving me the headache, but is there anyway i can get a firewall up and running on my current set up?
