List of ports to open between web server to middle tier in R12 DMZ,isupplier
Hello,
We are trying to implement Isupplier in DMZ. The current configuration has shared APPL_TOP and three trier architecture.
1> Apache/forms are running on one server
2> Concurrent processing is running on one server
3> Database is running on one server.
We are planning to add a load balancer and two web server with shared appl_top among them in DMZ for Isupplier. I know that sqlnet port needs to be open between web server and Database server.
Can some one share , do we need to open any port between (External web server which hosts Apache/forms and is outside firewall) and Concurrent processing server? May be FNSM listener to view report or Concurrent request output/log file?
