I wonder whether someone could shed some light on this:

I have a number of computers running win95/win98 on a LAN using TCP/IP. We
are connected to the outside world via an ADSL (Nokia M10) modem which has
a static IP address. I have setup a pinhole in this modem so it routes
requests via port 80 through to one of the machines on the LAN which has a
web server running (internal IP address of this machine is 192.168.0.21,
listening on port 80 as well).
I have two domain names, call them "www.aaa.com" and "www.bbb.com" which my
ISP points to the static IP address of the ADSL modem.

Everything works of sorts , but whether a surfer tries to connect
"www.aaa.com" or "www.bbb.com" you get the index page for "www.aaa.com" in
both cases, so "www.bbb.com" just gets ignored.
Any suggestions to fix this are most welcome.

Also, once a surfer has connected to the site (either one) it shows in the
URL bar of the browser the modems IP number (like "http://203.96.91.128/")
rather than "www.aaa.com"

On another list I have been told that this is caused because the DSL modem
is actually passing the HTTP requests to your internally masked server
(private IP subnet) it is doing so by the older method (HTTP/1.0?) of
using the IP address and NOT the hostname. Since the HTTP requests are
made by IP address the Web server has no hostname for which to match up
against therefore it chooses the default vhost (i.e. aaa.com). This same
behaviour occurs with clients running older web browsers which also
request by IP
(instead of hostname), even on servers NOT behind a firewall. I
believe this was an HTTP/1.1 thing that allowed HTTP requests by hostname.

Any suggestions to remedy this are most welcome.
