We have public IP subnets from which we configured few IPs on the devices with particular ports like 5865 and all other ports are block in router as well as firewall .. but when i do telnet to ports 80,21,143,110,25,5060,8008,2000 it is open.. this i got from nmap scan.
If i telnet with the IPs which are not in use, that also opens telnet session.. to dig more i have applied one deny ACL for port 80 then i see traffic and if i allow the port 80 then i see traffic on Fortigate too.. Im not sure what is happening.. hows these ports are opened when everything is blocked..
