Had no time to browse the full thread yet, but just my few cents: - Did you check TCP wrappers (/etc/hosts.allow and /etc/hosts.deny) ? Like entries for portmap, nfsd, statd, rquotad, mountd and lockd - A link I used regarding configuring NFS http://www.lowth.com/LinWiz/nfs_help.html through firewalls. Though your firewall seems to be open, maybe it helps to clarify some things.
