Yessss! This has enabled me to register. NAT is working good enough for
now.

Next question. To get the most out of my connection under windows 98
I had to tune tcp receive window (RWIN) and MTU. I can set MTU in the
ifconfig.sn0, but how can I effect the receive window of the sn0
interface to maximize my transmission speeds?

Thanks again!!!
