Domino remote access through firewall?

can anyone point me to docs on this problem:

I have a domino server on the private segment of my network (192.168.100.10) that is accessable internally as internalhost.mydomain.com.

Externally, I have port 1352 on the outside of the firewall mapped to the internal machine (192.168.100.10). The firewall is accessable externally as externalhost.mydomain.com. (external address is, say, 123.456.789.123)

When I create a new location document on a Notes client for outside use, specifying externalhost.mydomain.com as the mailserver, I get the following errors in the status bar when trying to connect:

Connected to the wrong server server1/Site/Domain using address: 123.456.789.123

and then:

Server externalhost.mydomain.com is not responding.

Is there something I need to do on the Domino server to allow access through the firewall as well as on the LAN?

Am I attacking this the right way? Is there a “best current practice” for this kind of scenario?

Any pointers would be appreciated.

Thanks very much.

OK, well I feel stupid answering my own post, but for the benefit of any other poor newbies, here goes:

what you do is, go to File-Mobile-Locations, and create 2 identical “Location” documents, called , say, Inside and Outside. On the Servers tab of each put the server/Site/Domain address of the mailserver.

Then, go to File-Mobile-Server Phone Numbers, and create 2 “Connection” documents. In the “Server” field of each, put the server/Site/Domain address of the mailserver. But on the first one go to the “Advanced” tab and choose your “Inside” location, and in “Destination Server Address” put the INTERNAL address of the mailserver (in my example: internaladdress.mydomain.com).

In the second one, keep the mailserver name the same, but on the “Advanced” tab choose your “Outside” location, and put the EXTERNAL address of the mailserver (in my example: externaladdress.mydomain.com).

Now the user can leave notes open on a laptop, and when they go home, they just connect to the net and switch their Location from the bottom bar.

Wahoo.
