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?


I used to work for a router/switch manufacturer and we'd get reports of 
various scanners freezing or resetting when they were either scanned or 
were transporting a scan. Reproducing these issues was sometimes 
difficult because you had to have the right set of ports hit in a 
certain time.

In your case, are you performing scans of the same exact target ports 
with both NMAP and Nessus?
