Wilmo Posted June 23, 2017 Share Posted June 23, 2017 I have an unraid server with multiple network cards. two of the nics are used on a pfsense VM to provide me with a virtual firewall/router. pfsense has my no-ip.com dynamic dns set up on it. pfsense also has some ports forwarded for PLex, Emby, Sickrage etc... When i nmap my ddns name from Server-A (In south africa) I can see only the ports I have specifically forwarded. GREAT! When i nmap my ddns name from Server-B (in the UK) I can see the ports i forwarded AND a load of other ports too! Like pop3, smtp, ftp, imap... LOADs of others that I have not specifically forwarded! When i nmap my ddns name from Server-C (also in the UK) I can see only the ports I have specifically forwarded. Please can anyone tell me what is going on?! I do not want these odd ports open. But apparently they only appear to be open from my place of work... which I have not specifically allowed in PFsense or anything. I just don;t understand why some ports can be seen from one place, and not the other! Quote Link to comment
ken-ji Posted June 23, 2017 Share Posted June 23, 2017 maybe your work place is intercepting those ports as they seem to be the common internet service that many work places do no want employees to be able to access directly. Quote Link to comment
