Having a host name point at your home IP address is no more unsafe than connecting a PC to the internet to begin with.

 

Opening ports to allow remote management is far more dangerous. It does give remote access, so encryption, strong passwords or better yet certificates/private keys are basically a must.

no problem

 

certainly i need to open some ports

i also can chage those ports in every pc so it will never be the same or the standard port number..

 

it is safe like this ?

what else can i do ?

Not really, no. As the saying goes, security by obscurity is not security. You need encryption (e.g. TLS or VPN) to make remote management as safe as possible. Changing ports will keep out the random passer by, but bots that are scanning IPs and ports will find and attempt to exploit open ports sooner or later.

Thanks a lot
