We cannot test pings or trace routes all the way, the ISP says their upstream provider, I think China Netcom blocks this kind of stuff and it is there policy and they block it both ways. I think they are one of the main pipes into China. If you have time, check out how far you can get and what you see to ip 211.155.170.161 and let me know. I get as far as Sprintlink Asia Pacific Region 203.222.38.42.
>From another location I get stopped at 210.82.1.29 which is China Netcom.

Send a larget packet out and set the wait time to 30 seconds or so. See if you are still seeing drops or extended delays. My full time job has a T3 from NY to Croyden and SF to Croyden and we see some horrible latency during different times of the day. I guess there's just not enough fiber in the ocean :). Sometimes the delays are inevitable. BTW, you should conduct these tests against the external interfaces of each location and not the VPN portion. If the external tests are fine then you probably have a problem with something in your VPN configuration. Without more details I really can't comment on it. We have setup a 5 legged VPN with 3 locations in California, 1 in Florida and Tennessee. We did it using Linux, poptop and pptpd clients. 3 of the locations are T1's and the other two are low end DSL's (IDSL actually). We get latency but never packet loss. In either event I would also contact the remote ISP and raise the issue with them.

We have setup a site to site VPN and I don't know if this is normal or what, but I think it sucks :(. Average response time is over 300ms and I am seeing about 15% packet loss. Response times and packet loss are jumping up and down constantly. Even right now when it is 3:00am over there, response times are around 250ms and packet loss is still up and down from %5 - 30%. We have a T3 out of our US office that is barely used. Pings and traceroutes are dropped somewhere in China, I think China Netcom or someone like that.
