'[OT]: PIC web server question'

I've been playing with a pic web server and now I
need some help.
My computer has 2 Ethernet board, one is connected
to a ADSL modem and the other to the pic web server.
The pic web server has an address of 192.168.0.3
the computer Ethernet board is 192.168.0.1 and the
other one connected to the ADSL is 200.221.41.219.
I can connect to the pic web server from my computer
but how can I access it from Internet? Do I need some
kind of gateway?

Friendly Regards

Octavio Nogueira

Yes you do Octavio.

Try WINROUTE from winroute.com

You might want to check out Internet Connection Sharing.  This is available
in Windows 98/ME/2000.  Here is an article about ICS.

http://support.microsoft.com/support/kb/articles/Q234/8/15.ASP

I'm not sure if or how to configure it to allow access to your PIC via the
internet.  You may have to set up Peer/Personal Web Server on your computer,
and provide a link to your PIC.

You do need a router of some sort and unless your ADSL service provider
allows you to have multiple static IPs, you'll need a Network Address
Translation (NAT) service to allow you to share the one IP you pay for with
the two devices (PC & PIC).  I believe ICS should accomplish this although
knowing Microsoft probably in some inefficiently obscure way.

I have a Netgear cable/DSL router which performs both tasks for me.  The
nice thing is that if I had a PIC web server (wish I had the time to make
one) my PC would not need to be turned on all the time.  Linksys makes
another competing model.  They both have come down in price since I bought
mine to maybe around $100US at CompUSA (!@#$%) or Best Buy.  The throughput
on these routers is much better than what you'll get running router
software on your PC, but it can be more expensive.

Hi,

You will not be able to acces it unless you install a
router / gateway / DNS.

Your internet address is 200.xx.xx.xx.
Your intranet address is 192.168.xx.xx.

This means it is (the 192.168.x.x range) , if you have
done it correctly, shielded from the internet.

You have to, some how, pass the incoming packets from
200.xx.xx.xx from  your computer to 192.168.xx.xx
(And back of course).

A router/gateway/DNS incapsulates the outgoing packets

from 192.168.xx.xx in such a way that when packets are
coming back it knows it has to be routed to
192.168.xx.xx again.


There are a lot of useful Linux Howto's (altough not
directly related to windows it still is good stuff to
read). Consider your PIC server as a computer on a
intranet and you will find what you are looking for !


grtz,


Simon

If you have an old 486 PC laying around, check out linuxrouter.org and
lrp.c0wz.com.

This is a micro linux distro that boots off a floppy disk.  With 2
network cards you can easily create a router with NAT, and more
importantly, a firewall.

Hi,

Don't want to start an OS war, but I use Windows 2K exclusively (we have
an ISP running exclusively on Win2K using a combo of custom and off the
shelf software) and may be able to throw some light on this..

Win98/99/ME Isn't designed to do anything of much in this area.. it is a
home user's platform, not a server platform so comparing it to Linux
really isn't valid in this case..

WinNT has some annoying problems with the TCP/IP stack and drivers.. The
inbuilt routing stuff wasn't the best.. But it could be beaten into
submission eventually if you didn't want to do anything too exotic :)
There were other packages from 3rd parties that did better. If all else
failed you could build the routing tables manually, NAT (network address
translation) was a problem though. I think the later service packs
helped a lot.

Win 2K is a dream!! It just works once you get used to what your doing
and what its expecting :) It is stable, fast and so easy to develop
complex application on.

We have several of our servers using Multiple NICs on not just the one
subnet, but the same IP address. This is a form of redundancy and also
load sharing.

This works because a lot of the modern switches understand this. We use
Intel switches and Dell servers. The server and the switch negotiate
some how and decide that each of the 100Mb channels are the same machine
so it will load share the data to it. Effectively you get a 200Mb link
to the server with 2 NICs. The OS just treats is as a single NIC -
almost, you can monitor it a tell if one of the NICs goes down.. Pretty
cool.

As for answering the question for the original poster, it _may_ (its
been a while since I've looked at this) be possible to use "Internet
Connection Sharing" to achieve what he was after (allowing access to his
PIC web server from the internet).

You will probably need to be running Win99 or WinME to get the version
of ICS that will do this for you though..

Give the PIC the an IP address on the private network address (say
127.0.0.5). Enable internet connection sharing on the dialup (it was a
dialup?, if not you may have problems getting ICS to work - can't
remember if this is possible) and then in the advanced properties
somewhere it is possible to forward particular ports to machines on the
private network. This is normally used for say a mail server.

Set up the forwarding so that port 80 (for instance) goes to 127.0.0.5
port 80 and it should then work - give people your IP address or name if
you have a fixed IP on your dial up and away you go. The traffic to port
80 will be automatically forwarded to the PIC web server.

If you need to support a web server on the gateway machine as well, then
give the PIC one a different port number.

Hope that helps
Ash.

Just to mention Winroute cause it is a good utility, and does NAT and
Firewalling and all sortsa junk on even '95 goto winroute.com and get it
just set it up to forward port 80 to the Ip.

i use it on one of my machines when its not running linux.
