    HiI,

    In Application server field, you can put Host Name instead of Server IP Address.

    But through VPN client you should enter IP address.

    Try that,

      First, if you have a basis team; contact them as otherwise, you might need to publish some confidential information online for deeper analysis.

      Assuming you can't reach them, go through the below..

      Connect using LAN. go to command prompt (start > run > cmd) and run

      >ping sape01.....com

      (record this IP --> IPA)

      Go to your command prompt (start --> run --> cmd) and run > ipconfig

      Note the IP Address... (eg: 10.716.65.254 --> IPB)

      Then connect your VPN and go to the command prompt (start --> run --> cmd) and run

      > ipconfig

      Here, you should be able to see two IP addresses, one which connects you to the internet (seen before) and second that is allocated by VPN...

      Do any numbers of VPN ip and server IP match (IPA)?

      -


      If they do match in atleast first / second octets.. then try connecting via sapgui where you need to replace Client App server : sape01.naptg.com with the ip address,IPA. eg(172.2.1.14). If you still cant connect, you'll need to provide the sap gui trace file.

      -


      If not, you'll need to contact your network team and ask them for the reverse proxy that allows you to access the private ip address of the servers.

      Thanks,

    Forget about your laptop (Just to clarify), Enter below details to configure a SAP logon pad entry.

    Description: Functionality of SAP System (Ex: Production)

    Application server: IP address of SAP server (Ask your tech team/helpdesk) for this

    System ID/SID: 3 character SAP System ID (Ex: PRO)

    System number: 2 digit SAP instance number (Ex: 00)

    If you have any helpdesk service, just contact them to add the logon pad entries.

    Regards,

    Nick Loy
