In our company we do have several mail server across North America…
From what I have read, we need to allow port 1352 from The Lotus Traveler Server in the DMZ to our mail server located internally.
If we have more than 15 mail servers, it means we have to open port 1352 for all of them if we want that users on that server to be able to use their iPhone with Lotus Traveler.
The firewall guy want to know if this is possible to have something more secure. Let say, a kind of proxy located internally… or something else?
We have not tested this in our labs - but seems a reasonable setup. On the Traveler server, connection documents would be needed pointing each mail server to the proxy - or the firewall would need to forward all traffic through the proxy. In general, the network admins are the ones to make this call…
My firewall guy had me send him the IPs of the destination servers. only those are allowed, I also threw in my Admin server so Traveler could get the account info from that address book.
Traveler is set up as a configuration server, relying on the admin server for Person doc info. In other words, the traveler server has no Person Docs.
