The safest mode to enable remote access (RPC) on LAN

Hello!

 

I would like to know what is the safest mode to enable the RPC?

My solution is: I made a new general rule in the Smart Firewall right above the rule "Deafult Block EPMAP" with the following settings:

allow connection from other computers (I listed the computers' IP addresses, there are two PCs)

the port is "local EPMAP (135)" and UDP+TCP.

I also checked the "Create a Security History log entry" option.

Is there any safer setting to accomplish this task?

 

Thanks
