NETWORK CONFIGURATION
Network data encryption occurs if you enable network data encryption on either side of a network connection. For example, if you enable encryption on a server's IBM® Lotus® Notes® network port for TCP/IP, you don't need to enable encryption on the TCP/IP ports of workstations or servers that connect to the server.
If you want the server to have one TCP/IP port for Notes traffic over the Internet and another TCP/IP port for internal traffic over NRPC, you can encrypt the port for Internet traffic and leave the port for internal traffic unencrypted.
Be aware that multiple high-speed encrypted connections to a server can affect server performance adversely. Encrypting network data has little effect on client performance. For protocols other than NRPC, you use SSL for encryption.
To encrypt NRPC communication 1. From the IBM® Lotus® Domino® Administrator or Web Administrator, choose the server for which you want to encrypt network data.
2. Click the Configuration tab.
3. Do one of these:
5. Select "Encrypt network data."
6. Click OK.
7. Click the Server - Status tab.
8. Do one of these so that the change takes effect:
