We've opened the usual ports on the firewall as per the SAP standard ranges (internal message server, public message server, 32xx/39xx, HTTP and HTTPS connections for both message server and application servers, 445 for SMB etc.), but we're still having issues getting the AAS working. It looks like a network/firewall issue so we've been investigating the logs but with no luck so far.
We've already installed a similar set up successfully for an ABAP stack (a different application running NW 7.0) at this customer but not for a Java stack. I can of course provide detailed information on the error messages seen but wanted to ask more generally first: has anyone had experience of a similar installation set up, and could point us to unusual/unexpected ports that need to be open, parameter changes that need to be made or similar gotchas?
