Nice post, it contains a lot of info, though I cannot see the problem at prima vista. Can you try to change the /24 part to the real IPs of the machines ? I had this issue today, for some reason I was not able to mount them. Also, apparently the export zone is Fedora 7, and you are issuing "mount" from Solaris box, what is the command line that you have invoked and what was the error message. The NFS version incompatibility could be possible reason, although personally I haven't ran into such troubles (or can't remember) - try scratching that problem with flag "-o vers=3" when mounting.

rpcdebug
rpcdebug(8) System Manager's Manual rpcdebug(8)
NAME
rpcdebug - set and clear NFS and RPC kernel debug flags
SYNOPSIS
rpcdebug -vh
rpcdebug -m module
rpcdebug -m module -s flags...
rpcdebug -m module -c flags...
DESCRIPTION
The rpcdebug command allows an administrator to set and clear the Linux kernel's NFS client and server debug flags. Setting these flags
causes the kernel to emit messages to the system log in response to NFS activity; this is typically useful when debugging NFS problems.
The first form in the synopsis can be used to list all available debug flags. The second form shows the currently set debug flags for the
given module. The third form sets one or more flags, and the fourth form clears one or more flags.
The value all may be used to set or clear all the flags for the given module.
OPTIONS
-c Clear the given debug flags.
-h Print a help message and exit. When combined with the -v option, also prints the available debug flags.
-m module
Specify which module's flags to set or clear. Available modules are:
nfsd The NFS server.
nfs The NFS client.
nlm The Network Lock Manager, in either an NFS client or server.
rpc The Remote Procedure Call module, in either an NFS client or server.
-s Set the given debug flags.
-v Increase the verbosity of rpcdebug's output.
FILES
/proc/sys/sunrpc/{rpc,nfs,nfsd,nlm}_debug
procfs-based interface to kernel debug flags.
SEE ALSO
rpc.nfsd(8), nfs(5), syslogd(8).
