Jan 07, 2016 · Hello, i have CentOS 7 on a OpenVZ VPS and i see iptables is somehow failing to start: Jan 06 22:06:09 name iptables.init[111]: iptables: Applying firewall rules: iptables-restore: line 14 failed This is /etc/sysconfig/iptables # sample configuration for iptables service # you can edit this
iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -j SNAT –to-source your_vps_ip iptables-save. Since we can’t use the MASQUERADE command, we need to use SNAT. Also only full interfaces are supported (So venet0:0 isn’t compatible with the -o option). That’s why I cover this on a static IP based configuration. Dec 07, 2013 · IPTables allows the address to be handled by the NAT Table and other broader perspective that relates to QOS (Quality of Service) by Mangle Table. Mangle Table contains 3 types of rules, namely: Types of Service, Time to Live & Mark Settings (I will post a detailed post in later time regarding these).

Iptables is the firewall utility inbuild in Linux systems. It includes rules for securing the system. This is applicable for both incoming and outgoing connections. Mostly, we use iptables to manage packet filtering. It allows us to block connections from IPs, ports, etc. Hence iptables make the system less vulnerable to attacks.
I have two servers, using one for prod and one for dev. They are with different providers, and one is running Xen and the other OpenVZ (both running Ubuntu but 8.04 and 10.10 respectively). I've been having an issue with the OpenVZ server setting up my iptables because apparently its missing some kernel modules.

This is a limitation of the virtualization system we use (OpenVZ), basic iptables rules are possible but not those who use the nat table. If this really is a problem, we can offer you to migrate to a other system virtualization (KVM) as we begin to offer our customers. SO I had to migrate my server to the new system
