Ephemeral pipe support
Ephemeral pipe support allows piped connections to cross a NAT (network address-translating) firewall without a broker partition file. Ephemeral pipe support is enabled when IP*.*PIPE connections cross a NAT firewall. If this default does not suit your network, you can disable ephemeral pipe support and use location broker partitioning instead, or you can force ephemeral connections to be used even when piped communications do not cross a NAT firewall.
Ephemeral pipe support and location broker partitioning for address translation are mutually exclusive.
