[Shorewall-newbies] Re: tcpflags SYN+FIN -- I use nessus from a pc inside the firewall

Nessus was running from a PC inside the firewall. Since the tcpflags are
set on the same interface, I thought the TCP SYN+FIN packages will be
dropped no matter where the source hosts are. I guess that's the
problem, but why?

Do you still need the status file?

Thanks a lot.

I will try to determine what is happening.
