I have implemented the f_setup_session() callback in the snmpTCPBaseDomain.h/.c files. This callback obtains the port number and copies that into the session object. Then from the session object, the local_port is available while processing the SNMP requests. I am happy it works and that we can use this local_port in our software, that is so helpful. The patch with the above modification is attached. It would be so great if this patch can make it in the official tarball of Net-SNMP. Thank you for the suggestions and all the help all along.
