But as I said the nfs shares seem to work fine, I can read and write to files on them.
Yep, everything will look fine until an application on your client tries to lock a file, and then it will hang forever. Locking files during editing is pretty common, so I'm surprised you haven't seen problems yet.
You should do one of:
1: Update the client fstab and use NFSv4 instead of v3. In most cases, this will be the simplest and best fix.
2: Update the server firewall rules to allow all traffic from clients. Not recommended.
3: Update /etc/sysconfig/nfs and configure the system to used fixed ports for NFS services. Update your firewall rules to allow clients to reach those ports. More work than #2, but maintains security. This guide should help:
