I'm trying to NFS-mount a CentOS directory on my Fedora laptop, but I find I can only do this is I turn off the firewall on the CentOS server.
If instead I go to system-config-securitylevel-tui on the server, and allow NFS4, this does not do the trick. Nor does allowing port 2049.
What do I need to allow?
[I should say that the CentOS server is remote, and difficult to access directly; that is why I used system-config-securitylevel-tui, rather than system-config-securitylevel .]
