If the RPC programming model is appropriate to your design requirements, RPC
over LRPC (ncalrpc protocol sequence) will offer higher performance then raw
IPC using TCP/IP over the loopback or raw IPC over local named pipes. LRPC
is a local IPC mechanism that will not interact in any way with firewalls.

LRPC also provides a robust security model.

interface(127.0.0.1:port) to make the local communication happen (no remote
communication). The requirement is: the local IPC should not be blocked by
any (local) firewall (So any IPC/RPC based on window handle or network
cannot be used). Technically, by using Winsock replacement or LSP, you can
do this, but is there an existing firewall really do this? and should a
firewall do this?
