What is RPC Epmap?
RPC-EPMAP is the RPC “endpoint mapper”, which multiplexes several different MSRPC-based services over a single port. (Similar to HTTP vhosts, I guess.) Windows Firewall knows more than just TCP ports – AFAIK, it can block and allow individual MSRPC services.
How do I open RPC port 135?
To allow inbound remote procedure call (RPC) network traffic, use the Windows Defender Firewall with Advanced Security node in the Group Policy Management console to create two firewall rules. The first rule allows incoming network packets on TCP port 135 to the RPC Endpoint Mapper service.

I only say this with certainty because I have many hosts configured like this, and actually just tested it to make sure I wasn’t crazy 😉
