Hi,
My Host is CentOS 5.x. I also have
DEF_OSTEMPLATE="debian-4.0-i386-minimal" defined in /etc/vz/vz.conf
I can ping the Host Node's IP and the Host Node can ping the VM's IP
(both are public IP addresses) but I can't connect to the outside world.
There is one gentoo VM and one centos VM running with the same
configuration, but connecting to the outside world and allowing connections.
[EMAIL PROTECTED] ~]# cat /etc/sysctl.conf
# Kernel sysctl configuration file for Red Hat Linux

# For binary values, 0 is disabled, 1 is enabled. See sysctl(8) and
# sysctl.conf(5) for more details.
# Controls IP packet forwarding
net.ipv4.ip_forward = 1

net.ipv4.conf.all.send_redirects = 0

Additionally, there's no iptables rules currently.
[EMAIL PROTECTED] ~]# iptables -nL
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
[EMAIL PROTECTED] ~]#
Any ideas?
Thanks in advance!

i'm using a self-build debian etch template on a debian etch machine,
and i see the same thing, but it works without any problems since many
months
i have : DEF_OSTEMPLATE="debian-4.0-i386-minimal"
in /etc/vz/vz.conf
i've edited /etc/sysctl.conf according to the OpenVZ-wiki
and that's about it, works like a charm!
