Thanks for the quick replies!!
The IP addresses are on a x.240 subnet and the pipeline is set to pass all
traffic at this point. The reason that I would like to force an Internet
connection is so that I can then access my network from the Internet. I do
not want to do this all the time, but depending on where I am, I get more
throughput using the Internet than I do on a dialup connection. I really do
not care if every time my phone rings the server connects to the internet
because I do not get that many calls where it would make a difference. The
only thing that I have to do to initiate a connection is ping something to
force the router to connect.
Would it be possible for the server to assign the "unused" IP addresses of
my subnet to use to get back out? Or, can I use the public IP addresses for
the incoming traffic and NAT them to one of the other "unused" IP address or
the IP address of the server itself?
I do have a copy of Micro Images X-server software on my laptop, but I keep
getting an error about permissions. I will check it out. I had a problem
yesterday where I could not access my W2k Server until I shut down the Linux
box. I guess it has something to do with Samba. If I get same problem
again, I will shut down that service to see if that solves the problem.
I do not know about SSH so I will try to find something online about it.
Thanks again,
George

OK, this one gets a little more complicated, because you have real IPs to
work with. This will require setting the linux box up to act as
router/firewall after the Pipline router. With only 13 IPs, I should assume
they're a block on the same subnet? Or are they "random"?
Is the Pipline set to pass everything?
I'm not clear on your need to force an internet connection by ringing your
home phone, sort of a "wake-on-phone call" kinda' thing? If you have a modem
that supports auto-answer, and hopefully it is not a winmodem, there might
be a way run a script on answer that logs your home machine into your ISP.
I'll ask around about this.
Since this is a bit more involved than usual, and it's it already half-past
midnight, and I'll be in Albany in the morning 'till Sunday nite, I hope
you'll give me a chance to think it over. Forwarding real IPs through a
linux firewall is a bit trickier than simply masquerading reserved internal
network IPs with one real external IP.
.
The raptor should not interfere with an SSH connection, but it may get in
the way of a VPN through the LAN. SSH can also do X-ll forwarding for gui
enjoyment, so you might take a look at this.
I'll get back to you when I return from my weekend trip.
