michael_kent123 Posted January 12, 2013 Share Posted January 12, 2013 I recently ran nmap -sS -p1-65365 192.168.1.1 -vv on my Zyxel router.Here are the results:PORT STATE SERVICE21/tcp open ftp23/tcp open telnet80/tcp open http7547/tcp open unknownThe 7547 appears to be the CPE WAN Management Protocol (CWMP) which is this: http://www.axiros.com/knowledge-base/faqs-on-device-mgmt/cpe-wan-management-protocol-tr-069.html?no_cache=1This does assume that 7547 isn't something else.The other ports are open because they are part of the remote management (I realise I can set these ports to something non-standard or close them on the router).However, I'm not entirely sure whether 7547 should be open (http://www.o2help.co.uk/router-close-port-7547/).Any thoughts?Thanks!
