Re: How to know if a port is forwarded

[RobOEM <rd.seclists () gmail com>]

Well, you always have tcptraceroute, to trace single packets in TCP.
That will tell you, if the service responds to SYN or SYNACKs, and if
the firewall/router decreases TTL, whether or not there is one more
host in the route. Should work, might not.

In this guide we examine the importance of Apache-SSL and who needs an SSL certificate.  We look at how SSL works, how 
it benefits your company and how your customers can tell if a site is secure. You will find out how to test, purchase,
