This is a common result of your ISP's dhcp server *not* recognizing you
nor having any clue regarding what to do with you.

My guess is, that your ISP recognizes your win98 box by it's nic's mac
address and assigns it a functional lease.

However, it only recognizes that one (1) mac address and when you
surprise it with the mac address on your firewall nic, it doesn't know
who you are and decides to issue a lease on a non-functional address.

You have many choices, one of which is to take the nic out of the win98
box and configure it to work in your firewall and everybody ought to
live happily ever after . . .
