[vpn-help] Fwd: Internet connection dies after some minutes of heavy download traffic

[wosgien at gmail.com]

Hi,

I think it makes no sense for me to test these new builds. A "no error" test
result would have no validity.

I am very happy with lwf-8: The error did not occur for several day now, and
the normal VPN functionality works flawlessly.

Best regards,
Andreas
