Sapinfo and NAT Network Adress Translation

Hi SAP basis,

I have a problem when using sapinfo accros a NAT network.

I don't have have problem on a simple LAN.

My monitoring system, on which I want to install sapinfo, connect to SAP server with a NAT IP adress.

Real Adress IP of SAP server is on 10.2.2.X

I connect to it with 15.2.2.X

Yet it seems that the translation mecanism don't convert IP source. When I arrived on SAP server, i laucnh smgw and I see that IP source is 15.2.2.X, althought it should be 10.2.2.X.

Does anybody have any idea ?

Add a route ?

thanks/
