Which ports need to be open on a nfs mount server? And does the client need anything opening?
I tried setting 2049 udp and tcp, using system-config-securitylevel, but it doesn't seem to save the settings. First, am I trying the correct ports? Second, what am I missing in making the changes stick?

Here is what I don't get about that:
1) NFS4 doesn't rely on portmap anymore (according to RH documentation), so I assumed that 2049 was all I needed to worry about, however, unblocking that port doesn't do the trick.
2) How do you tell which version of NFS you are running? I am on 5.3. rpm -qi nfs-utils yields no results.

Thanks for the link. I used system-config-securitylevel to activate the firewall. Since I had selected NFS4 I had expected the shares to be visible. When they weren't I tried opening 2049 to tcp and udp, but they were not saved, so I'm inclined to think that the gui NFS4 option had already done that.
etc/sysconfig/nfs does exist, with everything commented out. The first section asks me to decide whether mountd is to use NFS_V1,2,or 3. In view of NFS4 being in s-c-securitylevel, this is confusing.
The ports mentioned in the file are much lower than the ones in the link you provided, by which I assume that they are intended to obscure the purpose. Is it wise to start by accepting the ports in the file until everything works, then try mapping in higher ports?
