Description

TCPIP_TcpIpAddress sets the bind address and the port on which the NRPC listener (Notes Remote Procedure Call) listens. This is the primary port for Notes client connections, server-to-server replication, and mail routing between Domino servers.
Format:
  • <Instance> – sequential number (0 for the first / only TCPIP port)
  • <IPAddress> – IPv4 / IPv6 address or host name; 0.0.0.0 = all interfaces
  • <Port> – TCP port, default 1352
If the server has multiple network interfaces, a dedicated port can be configured per interface (TCPIP1, TCPIP2, …), each with its own <Port>_TcpIpAddress.

Example configuration

Ports=TCPIP
TCPIP=TCP, 0, 15, 0
TCPIP_TcpIpAddress=0,0.0.0.0:1352

Notes & pitfalls

  • 0.0.0.0 is the default and binds to all available interfaces.
  • If a host name is given instead of an IP, DNS resolution happens at server start.
  • Separate multiple entries with commas / semicolons, e.g. 0,10.0.0.1:1352;0,10.0.0.2:1352.
  • Do not block port 1352 in the firewall – otherwise no Notes connections are possible.
  • The change only takes effect after a server restart.
