First, probably 50% of what I tell you will be useless, mostly because
I don't fully understand how your system is set up. I don't think you
could 'tell' me what you are doing and how, it is something that I
would have to see to be sure of what's happening.
1. IIS is a product that provides a web server, SMTP (and POP3 in
server 2003), and FTP support, and a few other things as well.
2. I think you are using ISA as your firewall. OK, I'm of the feeling
that an external firewall (and router, etc.) makes things easier. With
an external firewall, router, and NAT, things are much easier to setup
and make work, especially when sharing the load between multiple
servers. (Say do an FTP from hipson.net, and you are working with one
server. Send an email, it is another server. Ditto for Web
(www.hipson.net) for example. Trivial to setup.
I don't think you have that option, though is your internet connection
giving an ethernet connection to you? (does it have an ethernet port
that you connect to your server?) If yes, then adding an external
router, firewall and such is trivial--most of the cheap WiFi will do
all of this and they are under $100 US. If, however, your internet
connection is serial, USB or something not traditional network based,
it gets a bit messier...
Try to mentally disconnect IIS (the web/mail/ftp services) from ISA
(security/firewall/etc.) Now, try to figure out how (using ISA) to
route the required ports from the internet to the correct server (I
can't give you exact steps, I don't use it here... <g>)
I'll check one of my S2K3 books tonight and see if it says anythign
about this type of configuration.
I am familiar with ISDN (don't use it though, as it is many times more
expensive than my T1 speed DSL link.) and it is so old that the
interface could be anything! <g>
