Hello, I have setup a container with an OpenVPN server. I would like to restrict the connection between some OpenVPN clients, so I have setup iptables in the container.
What I have done so far: I have
  • set net.netfilter.nf_conntrack_acct=1 in sysctl
  • modprobed xt_tcpudp and ip_conntrack
See output:

[FONT=Courier New, monospace]proxmox3:/etc# lsmod |grep conn[/FONT]
[FONT=Courier New, monospace]nf_conntrack_ipv4 10143 7[/FONT]
[FONT=Courier New, monospace]nf_defrag_ipv4 1155 1 nf_conntrack_ipv4[/FONT]

In additon I have set to the container:
[FONT=Courier New, monospace]vzctl set 113 --iptables ipt_REJECT --iptables ipt_tos --iptables ipt_TOS --iptables ipt_LOG --iptables ip_conntrack --iptables ipt_limit --iptables ipt_multiport --iptables iptable_filter --iptables iptable_mangle --iptables ipt_TCPMSS --iptables ipt_tcpmss --iptables ipt_ttl --iptables ipt_length --iptables ipt_state --iptables iptable_nat --iptables ip_nat_ftp --save

[/FONT]However, when I start an iptables script in the container I receive
[FONT=Courier New, monospace]iptables: No chain/target/match by that name[/FONT]

and the firewall is not started. What can I do to make this running? Any help is welcome.

Best regards
Peter

im trying the exact thing. From what I've read everywhere, openvpn only works in a KVM not openvz due to restrictions on kernel modules.

If you get this working, please let me know, as i cannot install in a kvm as my cpu is not vt-x
