How To install SAProuter via SNC

The first thing we need to do, is to send a customer message to SAP   Support (component XX-SER-NET-OSS-NEW) and tell them to register the hostname and IP of our new Saprouter.

(In our case it is system name (hostname) = " **"and Public Ip =*******)
We have to register it with the official IP address (no internal IPs allowed), but it's allowed to use NAT in the firewall/router.
    Ports to be allowed in firewall/router (for Secured connection).
•    32nn: R3 Support Connection
•    23: Telnet
•    1503: Netmeeting
•    5601: PC-Anywhere
•    3389: Windows Terminal Server (WTS)
After we've received a confirmation from SAP that our Saprouter has been registered, we are ready to configure the Saprouter.
2.1 Go to and down latest SAP Crypto Library
2.2 copy sapcar.exe from exe/run directory of SAP Server
2.3    uncar the dlls and sapgenpse.exe from this using sapcar -xvf

If our Saprouter directory is C:\saprouter, these are the steps to follow.

STEP 1: Copy the unpacked files into C:\saprouter

STEP 2: Set 2 environment variables: SECUDIR and SNC_LIB according to the
guide we've downloaded.


STEP 3: To generate a certificate request, run the command -
sapgenpse get_pse -v -r C:\usr\sap\saprouter\certreq -p C:\saprouter\local.pse "<Distinguished Name>"

[In our case Distinguished Name =CN=**, OU=****, OU=SAProuter, O=SAP, C=DE available at system data maintaince and also at /saprouter-sncadd
 In this step certreq and local.pse files are created at C:\saprouter folder

Note:  We will be asked for a PIN code. Just pick our own 4 numbers, but we'll have to use the same PIN every time we are asked to enter one. This number is important because, the same number should be provided in future when our Saprouter secure certificate validity expires, so remember the PIN code. (In our case it is PIN:****)]

STEP 4: Then we have to follow the guide and request the certificate from> SAProuter Certificate

You may apply for a SAProuter certificate from the SAP Trust Center Service of SAP service marketplace
> SAP Trust Center Service in Detail > SAProuter Certificates 

SAProuter Certificate   "Apply Now" 

STEP 5: Copy the contents of the certreq file and paste the contents in the place provided there.

STEP 6: Then, clicked the "Continue" button. 

STEP 7: This will generate a certificate details: then copy the contents and create a file srcert (without any extension) in C:\Saprouter and copy the certificate details and paste it in this file.

STEP 8:  Run the command -
sapgenpse import_own_cert -c C:\saprouter\srcert -p C:\saprouter\local.pse

(This will create files dev_rout etc.  In C:\saprouter folder then create a file saprouttab (Without any extension and copy the following contents the  file.

STEP 9: To generate credentials for the user that's running the SAProuter
service, run command:

sapgenpse seclogin -p C:\saprouter\local.pse -O administrator

(this will create the file "cred_v2"    in  C:\saprouter folder )

STEP 10: Check the configuration by running command:

sapgenpse get_my_name -v -n Issuer
(This should always give the answer "CN=SAProuter CA, OU=SAProuter, O=SAP, C=DE")
sapgenpse get_my_name(to find the validity of license)
STEP 11: Create SAProuter service on Windows with the command :(download ntscmgr from Sap note 618053) and run the command  -

ntscmgr install SAProuter -b C:\saprouter\saprouter.exe -p
"service -r -R C:\saprouter\saprouttab -W 60000 -K ^p:<Distinguished Name>^"

STEP 12: Edit the Windows Registry key as below: (regedit)

MyComputer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SAProuter\ImagePath --> Change both the (^) to (")


STEP 13: Start the SAProuter service (there maintain logon user details as administrator and password.)

STEP 14: Enter the below parameters in OSS1 -> Menu - Technical Settings

a). Click on Change -

Saprouter at Customer Site:

IP Address:
Instance no:
