I rent a server, and my provider seems to be blocking nmap. Is there any other tools I could use to test my home network from the outside?
Also, does blocking nmap on a network provide any security?
If I try:
nmap scanme.nmap.org - I get: 1 IP address (0 hosts up) scanned in 0.50 seconds
nmap -sT -P0 -p 80 scanme.nmap.org - works
nmap -sT -p 80 scanme.nmap.org - doesn't work
Also, only -sT (TCP connect works), SYN scanning (-Ss) doesn't work.Seems like this could be some type of egress filtering.
