Hi,

just to clarify the situation:

1. You have got an Openvz server and several VE on it.
2. All VEs use venet0 interface.
3. Everything was OK but suddenly the following issue happened:
4. External computer tried to ping one of your VE and it was impossible.

Arp requests come from external machine to your server but your server don't reply because arp table doesn't contain appropriate record ("arp -n"). Am I right?
Then you try to use "arpsend" utility from HN. Could you please specify what did you do?
arpsend -U -i VE_ID -c 1 eth0
or something? Or may be anything else? And after you've typed that command you could observe that messages in /var/log/messages inside VE.

You didn't restart your network interfaces on HN. But may be anything strange in logs on HN or in dmesg?

P.S. I'm terribly sorry for these questions but I really wasn't be able to clearly understand your previous post.
