Changing the IP address of your SAP Server

Where do you need to change the IP address on the oss site, and how can you configure the saprouter?

You need to check your RFC connections in SM59 and your hosts file.

If you have set up any external ftp connections to your system, you also need to check if they use IP address or hostname.

If the SAProuter runs on the server you are changing the IP address, you must create a customer message for SAP and ask them to change the IP at their site. The IP address of a SAProuter must be from an official range. You must also update your SAProuter data and change the IP on SAPNet (system-data).

In saprouttab you need to adjust the IP as well.

How to Connect to your SAP System via SAPRouter?

On your SAPRouter, edit your saproutab file,
add P xxx.xxx.xxx.xxx yyy.yyy.yyy.yyy zzzz password) example:

P 192.168.145.130 10.240.7.10 3200 basis ---> Where 192.168.145.130 is your computer ip address on the internet, change this to * so that your saprouter will accept any ipaddress from the internet.

10.240.7.10 ---> is your SAP Server IP Address
3200 ---> 32 is constant, 00 is your PRD system number
basis ---> is the your password.

P * * * * ---> entry if you permit all

issue comman saprouter -n to reload the new saproutab file.

On your SAPGui logon screen (Remote Computer)
