/export   *.*.*.*(rw,fsid=0,insecure,no_wdelay,no_subtree_check)
/export/home  *.*.*.*(rw,nohide,insecure,no_wdelay,no_subtree_check)

is almost certainly not what you want - I just didn't spot it at first.
It doesn't actually say "allow any IP to mount this share", it says
"allow any machine with a 4 part FQDN for rDNS to mount this share".

You probably want, as a test, to put the subnet or IP address of your
test client in instead of the *'s, and figure out what the real range is
as you go.

If your clients are linux systems, you don't need the 'insecure' option
- that is only useful when the client systems are MacOS X or some other
OS that uses high source ports when mounting NFS.
