Hi,
1. Can you please show an output of the "ip a l" from HN?
|
[root@sls-ab2p14 ~]# ip a l
2: lo: <LOOPBACK,UP> mtu 16436 qdisc noqueue
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 brd 127.255.255.255 scope host lo
4: eth0: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 1000
link/ether 00:0e:0c:7f:0e:c7 brd ff:ff:ff:ff:ff:ff
inet 209.160.40.18/21 brd 209.160.47.255 scope global eth0

2. Are you sure that you have shown your routing table from HN when your VPS was started?
"ip ro l" on HN (when VPS started)
|
[root@sls-ab2p14 ~]# vzlist
VEID NPROC STATUS IP_ADDR HOSTNAME
101 16 running 209.160.28.232 vps101
[root@sls-ab2p14 ~]# ip ro l
209.160.40.0/21 dev eth0 proto kernel scope link src 209.160.40.18
169.254.0.0/16 dev eth0 scope link
default via 209.160.40.1 dev eth0

3. "arp -n" on HN (when VPS started)
|
[root@sls-ab2p14 ~]# arp -n
Address HWtype HWaddress Flags Mask Iface
209.160.40.1 ether 00:00:0C:07:AC:0F C eth0
209.160.28.232 * * MP eth0

4. You can use "tcpdump" to determine the packages behaviour.
When you ping VPS from the outside please provide us with such information:
- Is arp request comes to HN?
|
Using "tcpdump -nn -i eth0 icmp or arp" for these tests.
I see an arp request
There is no reply, every ping packet triggers and arp request but there is no reply.

- Is ping request comes to HN?
|
After sending some pings from outside I see no ICMP traffic on the HN whatsoever. I do see the arp requests as mentioned above however.

- Can we observe it on venet on HN?
|
I see absolutely no traffic on venet0.
| Quote: |
- Can we observe it inside VPS?
|
There is nothing, I tried tcpdump after entering the VE but saw absolutely no traffic whatsoever.
I cannot ping the HN from within the VE and I cannot ping the VE from the HW (HN-209.160.40.18, VE-209.160.28.232

- Can we observe this reply on HN?
|
No echo request from within the VE and no reply on the HN (of course)
| Quote: |
- Is it goes outside?
|
Nothing goes outside from the VE.
Thank you.
