I'm having a problem with an OpenVZ installation. We're seeing about 5 to 10 percent packet loss to the VE from outside. It looks like the gateway router does not like us. We're using venet.
You can see from this ping a gap of about 30 packets:
64 bytes from 10.80.5.71: icmp_seq=1025 ttl=54 time=7.16 ms
64 bytes from 10.80.5.71: icmp_seq=1026 ttl=54 time=7.17 ms
...
64 bytes from 10.80.5.71: icmp_seq=1055 ttl=54 time=43.1 ms
64 bytes from 10.80.5.71: icmp_seq=1056 ttl=54 time=7.12 ms
During this gap, tcpdump from HN's eth0 (it's gateway interface) shows this interesting ARP activity:
10:27:24.933754 arp who-has 10.80.5.71 tell 10.80.5.65
10:27:25.390579 arp reply 10.80.5.71 is-at 00:30:48:34:a6:d8

The gateway router is repeatedly asking about .71 but for whatever reason, is either not seeing the response or is just plain ignoring it. Unfortunately, it's a service provider's device and it's been pretty difficult to get the type of support I need in order to figure this out.
Could this be a config problem on my side or his router just braindead? It's a Summit Extreme.
Thanks in advance for any insight anyone may have.
