List,

    I have a question.......    I have a 128k ISDN line that just got
dropped in my house this saturday.  I also have, an Ascend Pipeline P50
ISDN router, a Cisco 770 ISDN router, and a Cisco 2501 router.  My
machines are 2 pentium pro 200's and a pentium 133.  Here's what I want
to do.....  I want to come from the ISDN connection to one of the two
ISDN routers (haven't decided which to use yet...if I use the pipeline,
I can set up secure access firewall in the router, if I use the Cisco
770, I need to get another Linux box as a firewall.....I know the Linux
firewall is better...but I'm on a budget.  :-)  )  OK.....  I want to
come from the ISDN connection to an ISDN router to a Linux box and set
up IP masquerading in the Linux box.  From that I want to go into the
Cisco 2501, out of that into a hub and into my two other boxes....You're
asking me.... John, why??  I want to learn Cisco IOS and here's my
opportunity!!  I guess it boils down to this.....  What do I need to do
to set up IP masquerading on the first Linux box?  What considerations
should I look at and why??  What I want to do is supply the 2501 with
either an entire "faux" subnet or multiple "faux" subnets so that I can
set up the router to do static IP's, DHCP, etc....etc....  Behind the
2501 will be my "Test" domain. Am I crazy, or is this too cool of an
opportunity to fool with some slick hardware?? Can anyone help me out
here or am I "out there"  ?  :-)  I'd appreciate anything you folks
could offer...........

  Thanks,

John Pierce
