Actually lotus notes works on a port that is off in the high ranges (do not
know exactly which one). Lotus notes can be encrypted as long as the person
encrypting to is in the Lotus notes address book.
All you would have to do is open up the specific port outbound from the
firewall to the server (client ==> firewall ==> internet ==> server) have
all data transfers be initiated from inside (replications) and you have no

Subject: Lotus Notes
I currently administer a firewall (FW-1 V2.1c, SUN sparc5, Solaris 2.5)
which protects our network of around 6,000 users. I allow all traffic
outbound (at the moment) and nothing inbound (apart from responses :) I
have 2 DMZs for email relay, cdrom, web etc.) One of our corporate
sections wants to connect to an external Lotus Notes server. As far as
I am concerned, our corporate stance is that the firewall is the point
of all network external connectivity. As I see it (I'm fairly new to
this, and no network expert) the two ways to connect are
1. via the Internet (which they should already be able to do)
2. via an ISDN line into an interface on the firewall.
The problem with 2. is that the server is 4,000 kilometres away, and an
ISDN line would be prohibitively expensive. I don't know what their
problem is with simply connecting via the Internet - perhaps the
transmission of unencrypted Lotus Notes traffic. I am simply trying to
get some ideas which I can present to 'them' before 'the big whiteboard
meeting' next week when all will be revealed. Any suggestions for
other ways ?
