Error of key and DNS leak.

OGZxAnKa

I have setup all correct until when I have to do sysctl -p. The error that prints is:

net.ipv4.ip_forward = 1
error: "net.bridge.bridge-nf-call-ip6tables" is an unknown key
error: "net.bridge.bridge-nf-call-iptables" is an unknown key
error: "net.bridge.bridge-nf-call-arptables" is an unknown key

I saw some other threads in other forums, all I read was it was a normal error and just ignore it after a reboot everything will fine and it was not
After ending the set up the vpn was working but I was getting a problem there was a DNS leak, when I checked the IP it showed the IP of the virtual s. also showed my DNS, so this is not really anonymouss. Im using a vps CentOs 6, 64 bits...!

# Controls IP packet forwarding
net.ipv4.ip_forward = 1

# Controls source route verification
# net.ipv4.conf.default.rp_filter = 1

# Do not accept source routing
# net.ipv4.conf.default.accept_source_route = 0

# Controls the System Request debugging functionality of the kernel
# kernel.sysrq = 0

# Controls whether core dumps will append the PID to the core filename.
# Useful for debugging multi-threaded applications.
# kernel.core_uses_pid = 1

# Controls the use of TCP syncookies
#net.ipv4.tcp_syncookies = 1

Config. When I try save it it prints the other error, I changed the information that it asked 0 to 1 and # the .net. This is causing my leak of DNS?

Part of config is now missing? But before it was there and it throw me the same problem.
