Hi DWS,

I copy ping results. it is one of client. 
The ping time out are accuring now, 
when i run another ping to same address or another address, no time out.
one is over 900ms, the other is 90ms..they are in the same network.
But, still bounding reply time. but the true IP reply time is under 30ms.

and when i stop one ping. it is started time out again as below.
I have over 10 clients on the other side.

do you have any idea?

Subject: RE: Stable NT based solution

Hi,

The CIPE-WIN32 Version 2.0-pre14 

I used NT4.0 to NT4.0 before but was not stable. 
So, I moved to 2K only one side.
The problem still occurred going to slowdown.
But, something strange.. 
When I in the slowness problem. it's looks like lost ping and over 1000ms..
no answer.. under 100ms ....over 200ms.. no answer..
if I run another ping at the same time on the same machine. then it looks
switch to another process priority.
for example one is around 500ms, but other is around 100ms...
but, some times it move to another level ie. 100ms..and some times no
response.
when i got the stop service. i saw very long ping response time and later .
Today it stop working again. needed reboot.it is working fine now.

I attached two ping samples it were started almost at the same time but have
each response time as below.
I hope you to find some clue.
and i will attach another sample lost ping and others.

sample 1)

Subject: Re: Stable NT based solution

Alright guys, give me a while to try and recreate the problem. Can anyone
say 
which version this affliction appeared in ?

Juergen, there is nearly a one to one correlation between encrypted UDP 
packets on the LAN and delivered plaintext packets on the VPN interface.
Can you confirm whether there are more packets arriving on the LAN (on the 
CIPE port) than are getting decrypted and delivered on the CIPE adapter ?

And which OS is getting the slowdown ?
