Lotus Domino is designed to listen for TCP/IP connections on all NICs in a computer system. If more than one partition is hosting the same service (NRPC, SMTP, POP3, IMAP, LDAP, or HTTP), fine-tune which partitions listen for which connections by associating each service's TCP port with a specific IP address.

For more information on binding services to IP addresses, see the topics Binding an NRPC port to an IP address and Binding an Internet service to an IP address.

As an alternative to using a separate NIC for each IP address, you can use a single NIC and still assign a separate IP address to each partition.

For more information, see the Assigning separate IP addresses to partitions on a system with a single NIC.

If you are unable to assign a separate IP address to each partition, you can use port mapping.

For more information on port mapping, see the topic Configuring a partitioned server for one IP address and port mapping.

Note As an alternative to port mapping, you can use port address translation (PAT), in which a firewall redirects the TCP port connection to a different TCP port. Both port mapping and PAT require advanced skills to implement correctly.
