RE: [users@httpd] Apache With SBC DSL

My advice would be to contact SBC sales and ask if you can get a static IP
address for your DSL line.  There are two reasons for doing this.  First, if
they offer static IPs, then you can be assured it will NOT be a 192.x
address (what would be the benefit of having a static 192.x address versus a
dynamic one?).  Second, if you're going to host web content out of your home
you should get a static IP anyway, just to eliminate the chore of keeping
your DNS in synch.

As for making your web server visible to the outside world, you'll want to
forward all incoming requests on port 80 to your web server.  Your DSL modem
and/or router should have this capability.  I have BellSouth as my DSL
provider and host a web server in house by forwarding port 80 to the web
server's IP.  Just remember that your outbound bandwidth is a fraction of
your inbound bandwidth, so your web clients will see some pretty crappy
performance when they request content from your server (their inbound will
be limited by your outbound bandwidth).

Finally, you shouldn't have any trouble sharing the DSL line with several
PCs.  Some of the newer DSL modems today come with DHCP and DNS servers
built-in, so that you can just plug an Ethernet switch into the LAN-side and
connect as many PCs as your switch will accommodate.  If your modem doesn't
have DHCP or DNS built-in, then you'll hook the modem's LAN output into your
router's WAN input, and then connect all of your PCs to the router.  In
either scenario you will want to use a static IP address for your web
server, so that you don't have to keep changing your port forward each time
there's a power outage and the server gets a new IP when everything reboots.

I hope this helps.

Subject: [users@httpd] Apache With SBC DSL

This is a little off topic. I asked the question before but I have
additional information about the problem and it may make a difference. I
have been told that the IP address given depends upon location so let it be
known that I am in the Detroit area of Michigan.

Currently I have dialup and use DynDNSUpdater to change my IP address in DNS
(through DynDNS.org).

I am going to be ordering DSL from SBC this week. I have my own PC and then
I want to have an Apache webserver on another PC. I want both hooked up to
the DSL. The DSL that I am ordering will have a dynamic IP address.

After talking to no less than 5 SBC DSL people, I know less now than before
I talked with them. I called tech support and asked if I will be getting a
routable IP address. (The person who will be doing the hookup for me told me
to ask that question.) The way she said yes caused me to ask the next
question. Is it a 192 address? Yep, you guessed it! The answer was yes.

Sooo, I need to find out how to work with the worse case scenario - that I
receive a dynamic non-routable IP address. How can people access my site
with a domain name if the dynamic address keeps changing and it is a private
network (192.0.0.0) address? My understanding is that the modem has the
dynamic non-routable address. If a router is next and then the webserver,
how can people reach the webserver?

I hope that I explained it clear enough. Thanks in advance for any ideas.

Mike
