For a while now I have had trouble using the interface names in iptables, such as: (edited)-A INPUT -i venet0:0 -p tcp -m tcp --dport 80 -j ACCEPT The problem is iptables does not seem to understand what venet0:0 is. I also have a rather odd network configuration. Output of ifconfig -a 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.

Active 5 years, 7 months ago. Viewed 945 times 1. So i want to create a nat rule for an 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.
