People,

I've got some external contractor using my Wifi network that needs to use their Lotus Notes 9 but complained that it cannot connect / synch to the server on their head quarter.

So may I know what TCP/UDP ports to be opened in the firewall so that they can use their Lotus Notes software back to their head office.

Thanks.

Port 1352 (TCP )
The Domino server on which Sametime is installed listens for connections from Notes® clients and Domino servers on this port.

Ah I see,

So TCP/1352 only for both directions ?
what about TCP port 25 to send and receive email and ports TCP 80/443 ?
TCP Port 8642 is used for Autosync notifications between device and server ?

NB Though 1352 is the default TCP/IP port number, it can be configured differently, by the Administrator of the system.

If there's a different setting (which is very rare), your contractor should be able to tell you, for his Notes client has to build up the connection. If there is nothing special in his Connection documents in his Name&Address book, you can safely assume it's port 1352. See the Destination server address in the Connection document that's used to connect to his server.
