Hi all,

I vave a serious problem after I upgraded my Debian Etch Host to the actual ovz-kernel. All was working fine before I upgraded.

The problem is that I can ping the VE from the HE, but the VE is not reachable from the outside world and the VE can't reach any outside systems. The HE is reachable as usual.

I searched the forum, tested the new debian-add_ip.sh, controlled sysctl, but nothing worked.

I would be really happy if someone has an idea.

thalia is my HN, www is one of my VEs:

thalia:~# uname -r 
2.6.18-ovz-028stab053.5

thalia:~# grep -vh '^#' /etc/sysctl.conf | grep -v '^$'
    
net.ipv4.conf.default.forwarding=1
net.ipv4.conf.default.proxy_arp = 0
net.ipv4.ip_forward = 1
net.ipv4.conf.all.rp_filter = 1
kernel.sysrq = 1
net.ipv4.conf.default.send_redirects = 1
net.ipv4.conf.all.send_redirects = 0


thalia:~# iptables -t nat -L && iptables -t filter -L && iptables -t mangle -L
