I am troubleshooting a issue that has a me a tad bit confused, and if anyone has a nudge in the proper direction for me that would be great. I have a vpn connection that has been working fine for a number of months (over a year really). One endpoint is here in the states, the other in Shanghai. This last week however, the transfer rates on the line have gone to pot. With this being a overseas connection, to China no less, it is complicating tracking down the source of the problem for me. I don't really believe that anything is wrong with the VPN software (OpenVPN 2.0.9 i386-unknown-openbsd4.0 [SSL] [LZO] built on Jan 5 2007), but I have noticed something rather interesting. Packet loss over the unencrypted link is sitting at roughly 2%, over the encrypted link it is 22%. Transfer rates over the unencrypted line is faster as well. I will put the server config at the end of this message as well. Load on the endpoints is fairly light as well, one host is a 733Mhz machine, the other is a 450. Any ideas on what might account for the difference in encrypted vs unencrypted traffic? Thanks for any advice.
