Hi,

The issue we are having with our router is when the Nessus SYN scan runs only, 
the performance issue occurs.  If we disable SYN scanning and run all the 
normal tests, then everything is ok.  The issue occurs before the plugins are 
run.

Thomas,

I think the Michel and Todd were on to something.

Ron,
Correct me if I am wrong but, the UDP and DOS plugins are being depreciated in 
the newer versions.

Thomas,
It wouldn't be too difficult to disable to DOS plugins in an attempt to try and 
isolate them as the cause?

I personnally would be intersted in the results of your findings. I'm sure it 
would be appriciated by the list users also.

Good luck.

Hi Everyone,

I am performing Nessus scans through a Vigor 2800 router to a client over 
the Internet.

When performing scans using the SYN scanner inside Nessus, the router stops 
working.  If I use the SYN scanner in NMAP, everything is fine.
When we had the older DLINK router in, there were no issues like this.

Has anyone seen something like this?

Tom.
