Mount command fails with connection timed out....port issue?

I am trying to give read access to a data directory one one linux host (Host A)to an application on another linux host(Host B).

I plan to mount the data directory /abc/data of Host A on Host B. The steps I followed were.

On Host A
As root, Edit /etc/exports and add an entry as
/mnt/dataA <HostA FQDN>(ro)
Restart nfs service as
service nfs stop
service nfs start

On HostB
Mount the source directory as
mount <HostA FQDN>:/abc/data /mnt/dataA nfs ro,rsize=8192,hard,intr,nfsvers=3,tcp 1 2

This configuration runs elsewhere (between Hosts C & D), but fails here. I suspect it is a firewall issue, but not sure what port request I should ask my netops team to open.

Any advise is greatly appreciated.

Thanks much.

111 and 2049 would be my suggestion (check with netstat on your server)

Thanks much.....I think it is 111 for us, since I see that port open between Hosts C & D, but not between A & B. I will give it a try.
