Default Blue linksys DSL switches

We have a blue linksys DSL box.

I am thinking of getting a static IP address for the
Linux computer and then running some web things from it.

But how would the rest of the world be able to see
this computer behind the linksys box?

Look into port forwarding on the LinkSys box.

Configure the linksys to forward the appropriate services (i.e. port 80 == http,
etc) to the computer's local ip assigned by the linksys' internal DHCP server.

The outside world will then see the computer at your static IP address.

I do not think the Linksys would be able to utilize more than 1 internet
IP, unless that is all you need (SBC Yahoo static packages include network
IP, WAN IP, 5 usable IPs, and broadcast IP).

If you want to use more than just your connecting IP, you would either
need their modem/router (installation cost), or another suitable router
(or Linux router). See http://www.dslreports.com/faq/3759

Your PPPoE connection would still configured as dynamic, but
you@static_ameritech.net for login name would automatically assign and
route your static IPs to your connecting PPPoE IP (new SBC Yahoo users
would use you@static.sbcglobal.net).

It seems like a need a new router. How much do
these run? I think I would just need one to handle
two ip addresses, perhaps one dynamic ip to keep
the windows machines on the internet and another
static ip to pass on to the linux machine.

Am I thinking right here?

I just wish I had gotten a Zyxel P314 when they were $109. The price went
up and I think was replaced by new model. If you did get a suitable
router, you could put your server on one of your static IPs and the
Linksys WAN on another one (which could protect other private boxes behind
it). Or if you initially only use the Linksys, you would only have 1
public IP, but could forward specific ports to specific private IPs like
you can now.

No. And the Linksys DMZ and port redirection features are still,
AFAIK, broken. My suggestion would be to build a linux system with 2
NICs in it and run your web, mail, and whatever servers on it, as well
as the firewall software that's built into linux. If you need a good
gui for the FW configuration, take a look at shoreline firewall
(shorewall). Don't forget to block ports 135-139 (inclusive) before
you do anything else.

Is there a difference between each IP?

Is there a difference between a usable IP and network IP?
