NFS and Firewalld -

[Bob Goodwin]

My NFS problems continue. The hard drive was replaced, Fedora 30 
installed and NFS is configured. I think the configuration is good, I 
followed the instructions anyway.

Firewlld appears to be a new stumbling block and I don't know how to fix 
it. I looked at the Firewalld GUI and there is nothing intuitive about 
it. If I stop Firewlld, showmount displays the exports.

[bobg@box83 ~]$ showmount -e 192.168.2.128
clnt_create: RPC: Unable to receive

"systemctl stop firewalld" on the server:

[bobg@box83 ~]$ showmount -e 192.168.2.128
Export list for 192.168.2.128:
/home 192.168.2.0/24

Any help appreciated.
