i have a netapp filer running nfs server and a redhat 8 client trying to mount the filer file system. the exports have been properly shared on the netapp filer and are being correctly mounted using an NFS client for windows (diskaccess). but i cant seem to be able to mount it on my redhat 8. i do it like this:
[root@phantom etc]# mount 172.16.50.145:/ /mnt/filer
mount: RPC: Timed out

this is the result of rpcinfo -p
[root@phantom etc]# rpcinfo -p
