Cannot Open R/3 Transactions from EP 5.0 External Services

Question

We are on EP 5.0 SP6, and because we are on SAP J2EE Patch 21, we are using IISProxy.dll as our ISAPI filter (instead of the SAPJ2EE Filter).
EP connects to our CRM system using SSO correctly when we run Enternal Services that point to CRM BSPs. Consequently, we know that SSO connectivity between the two systems is working.
But when we try to connect to ABAP reports using External Services (via SAP Application.Transaction Master iView), we receive a Page Cannot Be Displayed error. The External Services should open the standard SAPGui within the External Service. We know that this should work, as we have correctly openned these reports on our DEV box.
The error in the IISProxy.log file is as follows:
22:20:24 Global F-Init   IisProxy Filter 1.6.0.0 initializing.

Does anyone have any idea why the External Service will not open the SAP Gui? Any input will be greatly appreciated. Thanks.

Answer 1

Do you know HTTPS is allowed on your firewall? Do you use any type of load balancer? eg., F5 Big-IP .. If not put a network sniffer to monitor the traffic on your firewall to see why it displays "page cannot be disaplayed" error... Also, you may want to use Paros software to intercept HTTP and HTTPS data between server and client, including cookies and form field. This may help you to get some idea.

Let me know.
