CRM_UI Export to Spreadsheets problem

Hi all,

We are using SAP CRM 7.02. We've opened our CRM UI to internet for our customers and they use a link like crm.company.com.tr:8000/sap/bc/bsp/CRM_UI_START/Default.html

In activity list, when we try to export list to Spreadsheets, it tries to connect our local link and as normally we can't reach the page.

Where Do I need to change something for solving this issue? Does it that local link from icm/host_name_full?

Thanks

Tutku
