[Vpn-help] Significant connection stability improvement ...

[Matthew Grooms]

All,

I am very excited to be writing this email as I recently fixed a bug 
that has been eluding me for the better part of two years. It caused 
periodic connection instability due to mishandling of computed Diffie 
Hellman shared secret data. From a user perspective, this bug induced 
seemingly random disconnects in the form of DPD timeouts or a sudden 
loss of connectivity. Both of these issues were related to invalid key 
data being used by a negotiated security association. A new beta has 
been posted on the download page. If you have experienced connection 
stability issues in the past, please consider testing this build which 
also includes a few other platform specific bug fixes. Please see the 
release notes for more details.

With that said, the client is still somewhat susceptible to packet loss 
which can lead to similar symptoms. I am in the process of implementing 
fixes for this and other deficiencies. My lab has been reconfigured to 
artificially induce severe packet loss so it shouldn't take too long to 
identify and correct any lingering issues.

Thanks,

-Matthew
