I thought that it might go in there but I wanted to make sure that was
the correct way. Plus I am doing ipmasq for internal network. I have a
script that I am using. It works for me so far. Thanks for yours
though. I plan on putting the firewall on a p133 that is goin to be
gateway+firewall+dailout. Just haven't had the time yet.
Would I need something like diald on the p133 to accept dailout or is
there another way?
Thanks again
