partner <ip> not reached, connection refused

[Former Member]

Hello,

I have the following setup

Machine1 (host name: show-saprouter) running saprouter.exe. On this machine the windows firewall is completely disabled. Inbound rules TCP and UDP port 3200-3299 are open. Outbound rules TCP and UDP Port 3200-3299 are open too.

Machine2 (host name: show-S71) with my SAP system.

My goal is now to connect from my PC using SAPgui to machine1 with the running saprouter. saprouter (saprouttab: P * * *) now should forward me to machine2.

For SAPgui I have the following settings: IID = 00, SID: S71 (I checked them, they are correct), SAProuter-String: /H/16.58.245.70/H/show-S71/H/

If I enter the IP of show-S71 then I can connect without problems.

I also confirmed with ping that

PC-> machine1

PC-> machine2

machine1->machine2

is working.

Thanks

I found a solution.

SAP Logon is changing my SAProuter-String thus making it impossible to login... the tracer files etc. show that the SAProuter-String is altered and of course then it is not working.

Using Windows-Key -> sapgui /H/show-saprouter/H/SHOW-S71/S/sapdp00 works without problems.

You might try to add the following to your services:

sapmsS71 3600/tcp

If you run a Windwos OS, this is located in C:\Windows\system32\drivers\etc\

On most other OS it is something like /etc/services

Did this help?

Thanks for your reply. On which machine should I add these? My PC, machine1 or machine2?

[Former Member]

On your PC

I did it but sadly it does not work.

The log file on my saprouter machine shows that the saprouter is routing my connection to machine2 but the connection is refused.

Then may you should adjust the services files on your machine1 😉

I have added sapmsS71 3600/tcp to the services file on all machines(PC, machine1, machine2).

I have disabled windows firewall on machine1 and 2. In addition I have opened ports 3200-3299 TCP and UDP ports on machine1 and 2.

But it still doesn't work.

This is really strange. Let me recap:

If you try to login with IP everything is fine. If you replace the IP by the hostname, the connection won't establish. You are able to ping the following ways:

PC-> machine1

PC-> machine2

machine1->machine2

machine1 is your saprouter

machine2 is your SAP system

What about the firewall of your PC?

[Former Member]

Yes. I just confirmed it again.

pinging with the IP adress or host name both are working fine.

My firewall is not disabled because of company policy (I cant disable it) but I added saplogon.exe as an exception.

Maybe my SAProute-String is wrong? /H/show-saprouter/H/show-S71/H/

show-saprouter = 16.58.245.70
