We had a requirement where we need to connect SAP Gui from outside of Organization without VPN connectivity for training purpose.This scenario use three system:

  • SAP Server [Server name with IP]

  • SAP Router [IP]

  • Personal Computer [IP 99.656.148.81]

  1. Find IP address of your PC. I found below website handy:

Note down the value of “My Public IPv4 is:”. Let us assume the IPv4 we got is “99.656.148.81”.

  1. Find the SAP Server IP to which we want to connect and instance number.

Let us assume SAP Server name "" with IP with 00 instance no.

  1. Find the SAP router external/Public IP, make sure port 3299 is accessible from outside. Let us assume SAP router external IP is “”.

  1. Modify the saproutertab file with allowed entry

SAP server port 3200 is made-up of 32<SAP Instance no.>
#Remote connection for
P 99.656.148.81 3200​

If you want to give access from any where to anyone on this SAP server add below lines.
#Remote connection for
P * 3200​

  1. Restart SAP router to make the changes effective.

#saprouter -s  
#saprouter -r -K "p:CN=<saprouter_name_registered_with_SAP>, OU=<OU_id>, OU=SAProuter, O=SAP, C=DE"​

  1. Enter SAPRouter string in SAP Gui connection which is based upon your SAP router external IP.

SAPRouter string is built based upon SAP router "/H/<SAPRouter external IP>/S/3299", in our Example it will be  "/H/".

So here we learned how easy it is to connect SAP Gui through SAP router without any requirement for VPN connectivity.
