Message Server returns IP addres insted of hostname

[Former Member]

I need to connect to a R/3 System via the Message Server.

Connection to the Message Server works fine, but obviously it returns the IP address of the Server for my Logon group and not the hostname.

I am forced to use an internal IP address, that is NATed to the real IP address of this system, because it is hosted elsewhere.

But the IP Address returned by the Message Server is an external IP address and not one of the internal...

So - if Message Server returns a hostname, my problem should be fixed.

Can someone please tell me, if Message Server is able to send back hostnames and what must be changed in my Message Servers configuration?

What if you want to use the same logon group for internal / NATed addresses?

Let's say I use the logon group 'GROUP'. When I am inside the network, it works okay. But when I connect thru a regionnal office (NAT IP Addresses) The message server still tries to connect to the internal ip addresses and then the connexion fails.

One work-around would be to use two different logon groups but we are using R/3 transaction Iviews, wich would mean many sets of different iviews. For more convenience, it would be better to have a single logon groups that does it all.

Any suggestion?

Problem solved (by myself):

The Message Server sends the IP Address of the assigned SAP instance back.

Per default this is the address that is valid within the Network where the SAP System is hosted.

In order to tell the Message Server to send back the address, that is valid in our network, the Logon Group IP Address must be configured accordingly.

A second configuration is required for the SAP Gateway Service. This tells the Gateway that our external address is an alternative address for their SAP System.
