Dear Experts,
After scanning a public IP, the result shows ALL (from 1->65301) tcp ports open and ALL can be telneted ! what do you thing on this resault ? (see sacn resault bellow)

in the first time I tought that it’s a honeypot or there is a device that respond to all tcp connections, some thing like, after asking a person related to the company  , that has this IP,  he said me that there is only a Cisco firewall (without IDP) in front this IP, but he hasn’t confirm me if it’s a honyepot or not.

If it's not you're device or someone you know, I'd leave it alone.

It could quite easily be a honeypot, could be the FBI, NSA, or heck, even worse it could be the Music Industry/RIAA/MPAA. ;)

Or it could just be an improperly configured PIX firewall.
