Web Dispatcher and DNS

[Former Member]

Hi all,

I've an internal ABAP AS (Solution Manager) server with hostname XXX that I want to access from internet.

I've installed SAP Web dispatcher on the DMZ.

Also a subdomain of my company public domain was created, and on network level traffic is forward to SAP Webdispatcher: support.mycompany.com.

When I try to logon I get a DNS error because the URL returned has the internal hostname and port.

How can I make internal hostname transparent to the user, so that only support.mycompany.com will be showed ?

Regards

Hi,

It looks like you have tried to use wrong redirect directives in you web dispatcher configuration

>How can I make internal hostname transparent to the user, so that only support.mycompany.com will be showed ?

That is exactly the standard job of a reverse proxy. The most used reverse proxies ffor SAP systems are The SAP Web dispatcher and Apache. You can even in certain cases chain both of them.

I'd use an apache webserver and configure it as remote proxy with a rewrite rule. Check

There is no simple answer to your question as it is largely dependent on your web dispatcher configuration, whether you are using HTTPS/HTTP and the method used for each. Check the [Webdispatcher Documentation|http://help.sap.com/saphelp_erp60_sp/helpdata/EN/42/5cfd3b0e59774ee10000000a114084/frameset.htm] on the various uses.

Also make sure you have setup the parameter icm/host_name_full in your instance profile of your Solution Manager system which is your FQDN for the system.
