I was installed openvz and create vps using id 111. I was add 3 ip 192.168.1.2 192.168.1.3 192.168.1.4 :
[root@server ~]# ssh 192.168.1.3

and then i was edit my sysctl :

[root@server ~]# cat /etc/sysctl.conf
# On Hardware Node we generally need
# packet forwarding enabled and proxy arp disabled
net.ipv4.ip_forward = 1
net.ipv4.conf.default.proxy_arp = 0
# Enables source route verification
net.ipv4.conf.all.rp_filter = 1
# Enables the magic-sysrq key
kernel.sysrq = 1
# TCP Explict Congestion Notification
#net.ipv4.tcp_ecn = 0
# we do not want all our interfaces to send redirects
net.ipv4.conf.default.send_redirects = 1
net.ipv4.conf.all.send_redirects = 0

but after that when i login my vps, i cannot download.
[root@server ~]# ssh 192.168.1.3
root@192.168.1.3's password:

Hello,

you should install appropriate nameserver inside your VPS. Otherwise you won't be able to resolve externam names. If your VPS and your HN are on the same subnet "cat /etc/resolv.conf" on HN helps you to set appropriate nameserver inside VPS.

vzctl set 111 --nameserver YOUR_NAMESERVER --save
