Why would you want to block all of them. If your firewall is setup
correctly everything should be blocked coming in? There are a variety of
ports used for active directory and othere services. What kind of network
do you have? A good firewall blocking ports coming in is the way to go.
Just my 2 cents.

I'm sort of lost? Is your webserver in a DMZ zone or are all ports open to
all of your servers? Better yet whar are you using for routing? A Linksys
or someother broadband router. I personally use linux for my firewall and
it works great. All you need is a computer with TWO network cards you would
put you public IP on one and your internal ip on the 2nd network card. Then
you can enable routing between the two. I suggest redhat 9 or mandrake
something easier than the other linuxes.

It shound like you have two public IP's? I would just put you server behind
the router / firewall and just open port 80 and then what ever database port
you need open they are all different it all depends if your using mysql or
mssql etc...

Just use one IP and let the router do your NAT and filtering. I need to
know what router you are using 1st. I'm still not clear on your network
diagram?

Thanks,
Big

Thanks for your input. Here is how what I have

I have 2IP's, One static and one dynamic. From the DSL
modem, the feed goes to a swtich. From the switch, one
static IP goes to the server, and the other IP (dyanmic)
goes to the router. The server hosts a website, the
backend db and acts as an file server. The rest of the
computers are behind the router. The Router is a Linksys
Router.

The reason why the server is not behind the router is
becuase the site would time out behind the router. People
were not able to see the website. Therefore, that option
is out.

For the firewall, I was using ICF, but then I could not
get the users behind the router to see the shared files.
So then I tried using IPSEC, but I am don't think that I
have it setup properly. Right now there is no firewall on
the server which is just dumb by me. That is why I want
to know which ports Windows networking uses so I cn open
those and port 80

I need to get a good firewall program for the server,
which allows me to share files as well (but limit the
sharing to a specific IP address)

Any input would be great

Thanks
