Inside an Actiontec router

Closing CWMP and port 4567

Frontier/Verizon keeps 4567 open. They can do a lot of stuff through it To close it:

  1. In the console advanced/local administration enable local access
  2. get over the telnet local admin adn change enabled for cwsp to false

telnet ip.ip.ip.ip 4567

  1. Wireless Broadband Router> conf print /cwmp

set enabled to 0 now you might still have the port forward for 4567 but fret not, there is nothing listening on that port anymore test by browsing to the url in conf print /cwmp/attribute/InternetGatewayDevice/ManagementServer/ConnectionRequestURL
