[Former Member]

Hi,

I am trying to use use latest version of SAP GUI 720 with Windows 7 .

When I am connecting through Local Area Connection I am able to connet to the sap servers.

But when I am trying to connect through Internet via VPN it displays error

"""""hostname 'xxxx' unknown

Check your application server name

Do you want to see the detailed error desciption?

Yes/No """""

With same router string I am able to connect to SAP server through internet on Windows XP pro.

Not sure what is the issue

Kindly help.

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.

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,

Hi Thomas

thanks for your response.

Apologies for probably asking very basic questions as I have functional background.

Where to find Host name?

I have following entries given in application server : ATSSAPDEV

and in some cases sape01.naptg.com

Hi,

Just go to My computer Right click- Properties there u can get Hostname otherwise, you can go to

Start->Run enter cmd and put the name of Hostname.

Hi Thomas

thanks once again..

I got the hostname..

So do you mean

while connecting via VPN I should change the SAPGUI and put this hostname in the application server field ?

[Former Member]

Hi,

Through VPN you should enter your IP address ( like 192.162.1.1 ) with the field of Application server.

make it markable if you are done this.

Hi Thomas

it is getting a bit confusing.

Client Name : X ltd.

Client App server : sape01.naptg.com

My laptop ip address: 10.716.65.254

my laptop hostname :YH1300

Now crucial question :

2 Situations

via LAN Network connection

I should put in SAPGUI under appluication server : sape01.naptg.com..it is working fine.No issues there

but while connecting via private internet /VPN (say at home or remote location )

I should change SAPGUI Application server : put my laptop ip address ? or client's server? as indicated earlier if I keep

sape01.naptg.com then the connection doesn't work.

Hi,

That server IP address in the field of Application server. Not your Laptop IP.

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,
