No; ISA won't "buffer" any traffic - is receives, processes and acts on it 
according to rules.

Shouldn't ISA buffer packets that are coming thru the tunnel, establish a new 
SA and then keep sending 'em?

Hi Jim, 

I've tried KB907259 but that does *not* solve the SA Idle Timeout problem. 

In http://forums.isaserver.org/fb.aspx?m=2002001812 there is some discussion
if the re-negotiation of the QM SA could lead to broken TCP connections
within the VPN tunnel. I would like to hear your opinion on this issue. 

Thanks,
Stefaan

I spoke to the guy that worked that problem and wrote the KB.
He suggested that you try it to see if it works for you.
If so, we can get the KB updated to reflect your findings.
