Further to my problem below.
It appears that certain filter directives in iptables are causing the error and not the COMMIT, when I comment out these directives then my firewall inside the container works:
# Accept traffic with the ACK flag set
-A INPUT -p tcp -m tcp --tcp-flags ACK ACK -j ACCEPT
# Accept responses to DNS queries
-A INPUT -p udp -m udp --dport 1024:65535 --sport 53 -j ACCEPT
# Allow SSH
-A INPUT -p tcp -m tcp -s 34.158.176.17 --dport 22 -j ACCEPT
Anyone any idea what is "wrong" with these iptable rules ?
TIA

Hello,
I am trying to set up iptables inside a container. I see that iptables-restore fails always on the line with the last COMMIT command after the *filter rules.
My parameters in vz.conf are
IPTABLES="iptable_filter iptable_mangle ipt_limit ipt_multiport ipt_tos ipt_TOS ipt_REJECT ipt_TCPMSS ipt_tcpmss ipt_ttl ipt_LOG ipt_length ip_conntrack ip_conn track_ftp ip_conntrack_irc ipt_conntrack ipt_state ipt_helper iptable_nat ip_nat_ftp ip_nat_irc ipt_REDIRECT"
I cant see any descriptive error message other than the "line XX failed", which contains the last COMMIT command.
Any help would be greatly appreciated. I am running openvz on Debian Etch, self-compiled kernel 2.6.18 with openvz patch.
BTW: Iptables on the host itself does not complain and works.
Thanks
Geejay
