nfs mount w/o dhcp

Hi All,

I have Linux on embedded device and another linux machine, both
connected to bridge. which is not in the main network (no dhcp).
I can do ping, but  can't mount nfs from  embedded to  desktop.
If both connected to the  main network, same nfs mount works.

I want to solve it. My mount command is
mount -o nolock,tcp 192.168.1.1:/opt /.mnt/opt
Can i configure nfs on desktop somehow to solve it?
