http://forums.fedoraforum.org – I am having a whirlwind of trouble mounting a drive over nfs onto my FreeBSD machine from Fedora. I can mount from Fedora to Fedora using nfs (and its external IP) without fail, and I can mount from ubuntu to FreeBSD over NFS. I have set Fedora's SELinux to permissive with no noticeable change. I will try to provide as much information as possible. (HowTos)
