It would probably be more reliable if I was. Even better, why my VPN connection to HQ is so poor. Let's see you fix that, smart guy!

It's probably packet loss, or one end's upload speed is very slow.

ADSL and cable (or any asymmetrical) connections are not well suited for VPNs.

Trying pinging (more than the 4 done by default by Window ping command) the IP address of each side from the alternate and see if there is any loss, or large deviations. Running the ping while the VPN is up may also be very telling.

ping -t <host>

That'll keep the pings going until Ctrl-C is hit.

Ah, but one end has multiple OC3s, and the other end (mine) is 10MBit guaranteed burstable to 100MBit going through 3 redundant providers.

And what's your upload? Try http://www.speakeasy.net/speedtest/

If it's not that, I'd say it's a configuration issue with the VPN endpoints. What are you using on your end to establish the VPN? Just a session on your machine?

You probably don't know what they are using to serve the VPN on the other?

Symetrical on both ends. Downloads from MS, VMware, etc actually get pretty damn close to that 100MBit limit.

PaloAlto PA-2000 on the head end, PA-500 on this end.

Naw, seriously, I don't expect you to solve (or even really troubleshoot) this. We've been working on this problem for months. It's just really confusing and annoying.

One more question. Is it affecting more users than just you?

If more than one person is affected, I'd say the problem lies at the HQ. If they are serving a large number of VPN connections they machine doing the work may not have enough CPU power the handle all the encryption work. There are encryption accelerator cards to off load the computation (but they have to be supported by the VPN software).

Well, this is a site-site VPN, so I would expect all of us to get hit. At the moment I'm working off the idea that there's something weird in between our ISP's routers and HQ.
