    I think the more recent one is: tirpcsrc2.3.tar.Z
    (rpcsrc4.0 is really from a much earlier data and is only

    "transport independent rpc" as found in Solaris)

    I'd suggest (strongly) to filter everything incoming except
    the specific ports you want to keep open.

    And for outgoing traffic use keep state.
