Hi, I'm a new user into VPN's so I don't know much about this. But lets explain what's the problem (Before anything, sorry if my english isn't good) I bought a VPS on Host1Plus, also paid for TUN/TAP, but NOT for NAT, is this necessary? Because I've been following this guide [code]http://www.servermom.org/how-to-build-openvpn-server-on-centos-6-x/732/[/code] But when I type: iptables -t nat -A POSTROUTING -o venet0 -j SNAT --to-source 123.123.123.123 and iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -j SNAT --to-source 123.123.123.123(

Installing OpenVPN on CentOS x86 issue

Hi, I'm a new user into VPN's so I don't know much about this. But lets explain what's the problem
(Before anything, sorry if my english isn't good)

I bought a VPS on Host1Plus, also paid for TUN/TAP, but NOT for NAT, is this necessary?
Because I've been following this guide

http://www.servermom.org/how-to-build-openvpn-server-on-centos-6-x/732/

But when I type: iptables -t nat -A POSTROUTING -o venet0 -j SNAT --to-source 123.123.123.123
and
iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -j SNAT --to-source 123.123.123.123(<-I know that my IP should be there)
I get this:

FATAL: Module ip_tables not found.
iptables v1.4.7: can't initialize iptables table `nat': Table does not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.

Sorry if this is a noob question but I'm a recently user of this.

Another one:
If I run sysctl -p
I got

[root@ConnectLife01 2.0]# sysctl -p
net.ipv4.ip_forward = 1
net.ipv4.tcp_syncookies = 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

What's the problem with that error? Im a bit confused

Thanks in advance

if your VPS is a VZ based container then thats why your iptables command is not working...

now, if NAT is necessary or not ,it totally depends on what exactly do you want to do.
