Webdispatcher 7.42sp33

We are setting up a proof of concept and wanted to used WebDispatcher. I installed on SUSE WD 7.42 and patch 33.  WD is running fine and I can access from the lan both Admin and MMC.

Initially we want to access one system but set WD up that will allow access to multiple.  We are fine using a single port, so expect to use host as the filter.  so for example host1 and host2 filtering on

we have setup the

wdisp/system_0 = SID=ONG, MSHOST=host1, MSPORT=8101,


and indeed in webadm we can see ONG details, so I suspect this connection is working fine.

The Webdispatcher ports are setup as follows


# SAP Web Dispatcher Ports


icm/server_port_2 = PROT=HTTP,HOST=xxxwd1,PORT=8100

icm/server_port_0 = PROT=HTTP,PORT=8888

icm/server_port_1 = PROT=HTTP,HOST=localhost,PORT=81$$

icm/HTTP/admin_0 = PREFIX=/sap/admin,DOCROOT=$(DIR_DATA)$(DIR_SEP)icmandir,AUTHFILE=$(icm/authfile),PORT=81$$

webdispatcher is WD1 on host xxxwd1 (again this is just a proof of concept)

I have also tried

So I expected that everything coming in on to go to host1.

It isn't and not only that I can't see WD1 ever getting any calls apart from my web access on port 8100.

this SUSE system has the firewall turned off.

port 8888 is forwarded to WD1, for testing I forwarded port 8888 to host1, to make sure our network wasn't the problem, and when I do that I can get to NetWeaver on host1.

Any suggestions on what I am doing wrong or how I can better test it to see traffic on 8888 going through WD1

    start your WD administration console and check if there are active services. If there is no active service you have to reconfigure WD.

    After that goto Backend systems and check if there are valid application servers. If there's none, WD can't communicate with the backend system.
    If the backend system is ABAP: Is ICM configured correctly. Try with ICF service ping.

    What does the WD trace say?

    kind regards,
