Dear Jehan,
OpenVZ container does not require to enable additional capabilities,
default settings allows to use iptables inside container.
However by default netfilter is restricted,
most likely you need to change it by using "prlctl set --netfilter"
--netfilter <disabled|stateless|stateful|full>
Restrict access to iptable modules inside the Container. The fol-
lowing modes are available:
disabled -- no modules are allowed.
stateless -- (default) all modules except NAT and conntracks are
allowed.
stateful -- all modules except NAT are allowed.
full -- all modules are allowed.
btw. prlctl works as "vzctl --save" in any cases, it saves the setting in
configs.
Thank you,
Vasily Averin
