SM59 RFC connection via router

Question

Hi Friends,
I want to connect from one system to another via rfc and DYNDNS.
The problem is I have a DSL router. The way is ERP6(1) -> DSL Router ->ERP6(2).
When I use the normal sap logon, I can logon with "server.dyndns.org" to ERP(2).
In DSL Router I configerud the "Nat Rule" 123.123.2.2:3203 and it leads me automaticly to the logon screen.
But then I try the RFC connection, it does not work.
In RFC I give "server.dyndns.org" as target machine.
Do I have to call the target machine with port and how does the entry looks like?
Thanks in advance
Jimbob

Hello Jon/all,
many thanks for your recommendations.
Our RFC-connection from SOLMAN to the satellite system via SM59 does not use load balancing and looks as follows:
/H/saprout1/H/193.84.171.507
We also allow the connections to the message port (36xx) within SAPROUTTAB.
Colud you kindly explain what are the settings of:
1) RZ21 --> Connection Data and Monitoring options --> Router String
The current CCMSPING entry is:
Connection Data and Monitoring options:
Message server host name: 193.84.171.507
IP Service Name: sapms<sid>
Router String: /H/saprout1/H/
2) The entries within SAPROUTTAB
3) The entries within SERVICES and HOST files
Thank you very much!
