I'm trying to access an nfs share from a server in one location on
our wan (10.33.1.2) from our server at the shop (10.8.24.7). I am
seeing time outs when I try to mount the share. When I look at the
log on the server supplying the share I see what appears to be an
authentication success(?). The log says the message is repeated six
times (as if the requesting server never hears the authentication
success message?).
How does this strike you guys? Might I be fighting against blocked
ports on some of our vlan's?
I would check your router/firewall logs as rpc.* is a common thing to
block. Have you ran tcpdump on each of the hosts to see if requests
and responses show up on both sides?

[root@fvserver /etc]# cat hosts.deny
portmap:ALL
lockd:ALL
mountd:ALL
rquotad:ALL
statd:ALL
[root@fvserver /etc]# cat hosts.allow
portmap: 10.8.24.7
lockd: 10.8.24.7
rquotad: 10.8.24.7
mountd: 10.8.24.7
statd: 10.8.24.7
Not sure if this is done for security reasons, but tcp wrappers will
only check tcp traffic. You will note in rpcinfo that these services
are also present over UDP and could still be accessed by others.
