Actually it works just fine when I turn off the firewall on the CentOS end. Could it be that even when I am trying to mount over the TCP the NFS client on the Mac OS X side still tried to connect to some UDP port? I am asking that because everyone else mounts just fine with the firewall up on the server end. Boris.
