No, I am nor sure. I tried using 11.x.x.x on the xl0, but all routing out
of the machine stopped along there somewhere. It may have been the xl drivers
that don't seem to play well with multiple copies running.
I have the outbound interface NATed, so using a live subnet number
shouldn't be a problem. Or maybe just go to one of the other 1918 values.
Thanks; I'll give that a try again today.
