Our environment is split up into multiple customer networks.
For this specific customer we don't use the firewall feature (so we have a permit any rule).
the filtering (fire-walling) is done on a other place in the network (for this client specifically).
And if you scan the ip addresses for this client you`ll find the ports 5060 and 2000 open.
I find it strange that specific these ports are open and not the other like 22, 25 enz. (These ports are closed at the firewall on the other place in the network). The Fortigate marks these ports as open but at the back of the network they are not open.
So the question is how can i make NMAP scan not see the ports (5060 & 2000) without closing specifically these ports (Other applications use these ports as swell).
WY do i see these ports open in the first place, never ask for this.
Its a difficult to explane the situation, i hope i made it a bit clear so.
Thanks in advance
