We have an HP-UX 11i server running inside of our private area with files on it. We have a Linux Enterprise Server 3 in our DMZ. We want to set up a nfs mount between the two. The linux server will mount a drive from the HP-UX machine. I would like to know how to lock down the default ports that is used on the HP-UX machine to listen on so that we can open a default set of ports from the DMZ to the private space. Everything is open from Private to DMZ. I would like to know commands used and files that need to be created mostly on the HP-UX machine to make this happen. We have done this with linux to linux and were able to open a set of ports that we specified from dmz to private but we mounted the dmz dirve on the private machine.
I am not the Unix guy so I will have to relay with our Unix team which will delay my reply back. They don't know how to do it and asked me because I do network security.
Thank you for the help.
