Error firewall iptables in container with zentyal

[pablov2]

Hi all,

I have a Zentyal 2.2.4 working in a container openvz in proxmox 1.9: Linux 2.6.32-4-pve #1 SMP Mon May 9 12:59:57 CEST 2011 x86_64 GNU/Linux

Linux zentyal2 2.6.32-4-pve #1 SMP Mon May 9 12:59:57 CEST 2011 x86_64 GNU/Linux

The problem is some rules of iptables and firewall module that cut the launch module and I get some error and some rules without adding. I have found this errors:

zentyal2# /sbin/sysctl -q -w net.ipv4.tcp_syncookies="1"error: permission denied on key 'net.ipv4.tcp_syncookies'

I have try adding this in host in /etc/sysctl.conf but it continues failing... Any idea?

maybe not related to your issue but you use an outdated kernel - upgrade to latest.

Finally, I have commented the line in the firewall module and it is working fine
