RFC redirected to sapdp instead of sapgw

[Former Member]

Hello

I have two RFC connections to two different partners; Both from ECC to ECC through our saprouter. And both partner systems have a logon group

or me the connection should be something like :

our ECC -> our saprouter (port 3299) -> partner CI (port 36xx, sapmsSID) / allocation to an AS -> partner AS (port 33XX or sapGWxx)

For the partner 1 everything is OK

We copy and paste the configuration for partner 2 and we get the following error message :

• Trace file opened at 20120126 172830 CET SAP-REL 701,0,137 RFC-VER U 3 1238

The saprouttab is OK

the etc/services are filled with sapms SID, sapgwXX and sapdpXX

From our saprouter I can contact the partner 2 systems on 36XX, 33X but not 32XX (because of our firewalls)

i will check with our partner, if the RFC user is of type "communication data"

It seems that I will need to open the firewall on ports 32XX ? Can somebody confirm this ? Can somebody explain why for one partner I only need 36xx and 33xx and for the other partner I need 36xx, 33xx and 32xx ?

Thanks in advance for your help and advice,

Thomas

Hi Thomas,

Usually ports 3299 for the router and 32XX (sapdp) for target system system-number should be enough... Check that the ports are not been blocked.

Hi,

Thanks for your answer but from my point of view, the ports for RFC are 33XX not 32XX

The fact that for the first partner it's working with 33xx seems to confirm that

In "tcpip ports used by sap" I find :

Dispatcher 32NN

sapdpNN

3200 3200-3299

sapdp00-sapdp99

SAP Dispatcher, used by SAP GUI for

Windows and Java

Gateway 33NN

sapgwNN

3300 3300-3399

sapgw00-sapgw99

SAP gateway, used for CPIC and RFC

communication

Small info hope it may helpful

36XX is message server port it should mainly required for load balancing between Dispacters and communication from Gateway

32XX Dispatcher port

33XX is gateway port - Reuired for communication between two SAP systems
