    Quite honestly, I don't know. Having two subnets just sort of happened
    when I was trying to switch from Samba to NFS. After some
    troubleshooting and advice from this list, NFS started working. NFS was
    able to use the static addresses and I was still able to access the
    Internet. The current problem occurred when I installed 10.0 (boxed set)
    on my laptop. I just want NFS and Internet access to work. If you see a
    way to get me there, I'll work with you as long as you're interested.

    Question. It appears that the router is also a DHCP server. That means
    that I do not need to activate DHCP on any of my machines. Right?

    I've set the router to start IP addresses at 192.168.1.2 and to issue a
    maximum of 50. Now if I configure all my network cards to use DHCP, NFS
    should work on all machines and all machines should be able to access
    the Internet. Right?

    And that's the way You can let all

    Given my objectives, is there any reason to have a subnet with static IPs?

    Okay. I see that.

    Thus far, your comments have been the most help. Please bear with me.
