Hi, I've been running a few Dahua bullet cams and and just added a few more turret and PTZ versions. Very happy with them and primarily use them with my Milestone server.
I've heard these cameras "phone home" so I want to control external comms a little. At the router level, I'd like to blacklist all ports not used for the purpose of email notifications. I'm using gmail which works at port 587. I blacklisted all ports other than 25 and 587 but am getting email test failures at that setup. Success when not blacklisting, so there is a port dependency I'm not aware of.
Any recommendations on getting this working or otherwise securing my cameras better? Obviously firmware updates and password are table stakes. I would deny them access to the gateway server and view exclusively through Milestone but want to get email working if I can... Already killed port forwarding to my server and viewing remotely only through a VPN.
