setting up nfs in 12.3

I'm trying to set up my nfs shares between my local boxes, one is opensuse and one pclinuxos. I can ssh
between the boxes, but when I export the file systems from my opensuse
box, my other machine doesn't see them. They're on the same 192.168
net, so is this all internal zone (that's not explained in the help
anywhere)?

Thanks,
Lorne
