Settings for PPPoE connection?

I`ve an interface that gets IP and gateway from a DHCP on a network
and the same interface has an PPPoE connection that assigns a real IP
address and a real gateway.
the problem is that I want this real ip to be the one for any external
connections TO my server. but don`t know how exactly to configure
it .. tried several times both with the local IIS server settings and
server`s NAT congifuration but no success at all.. there`s no access
from outsinde .. can anyone help me in simple steps how to accomplish
this ? 10x in advance

If you are trying to perform both internal LAn and External LAN roles
on the same Network card, this will never work. Install anoter
networok card, and label them accordingly and you will have your
solution

hm .. no,no mixed roles. I just want to access the server from
internet, with the IP that the server gets from the PPPoE connection.

This is on a workstation, I hope... not on your server. Servers should have
static IPs.

I'm confused by the use of "on the same interface".

I'm not sure I understand your configuration or question, but basically,
don't use PPPoE on a network interface ...have a router/firewall appliance
handle it. I'm also not a fan of multihomed DCs; if you're using ISA, you
need two NICs, but if you aren't, you need only one (with a decent firewall
appliance).

So more detailed describtion goes as follows :
This is THE server that has an NIC with NO static addresses assigned.
the ISP works with 2 DHCP servers, one that gives my NIC an internal
ip address smth like 192.168.0.183 and by this NIC I make a PPPoE
connection that gives me the real IP address.
so there are two connections both with Ip addresses and GW and so
on .. both dynamic (auto configured).
the goal is to connect (web,ftp) to the server from internet by using
the real ip address.
so any of this settings is applicable for changes cause ist the ISP
that works this way ..

This is not good. Your server needs a static IP.

It doesn't matter what your ISP does.....

I don't follow, but you need to get rid of that configuration anyway. I'm
not sure how you got here, but it's not going to work.

Yes, which is why you need to fix your configuration.....

You need a router/firewall between your ISP's modem/router and your network.
Your ISP's modem/router should not be doing NAT. It can do DHCP and assign a
dynamic address to the WAN interface of your router/firewall.....and then
your router/firewall will do NAT between the public and private networks.

Get rid of whatever PPPoE stuff you've got now - get the router/firewall
appliance connected, and run the CEICW. Your workstations & server will
point at the static LAN IP of the router/firewall. Your server will have a
static IP on your network. Unless you are using ISA, I suggest that you use
only one NIC on your server.

When you have all of this working, set up the port forwarding rules in your
router/firewall - 25 for SMTP, 443 for HTTPS, 4125 for RWW/Remote Desktop.
Forward them all to the LAN IP of your server. From the outside, you can
then access your server using your public IP address (that which is set in
the WAN interface on your router/firewall).

If you have a dynamic public IP, check out www.dyndns.com - you'll want a
Dynamic DNS account. I like to use the Dyndns updater software running as a
Windows service on the server, instead of having it handled by the
router/firewall - this is recommended by DynDNS. There are other options,
such as www.no-ip.com, and so forth.

For firewall hardware, I like SonicWALLs, but even a simple NetGear/Linksys
would accomplish this, although less securely.

You should probably ask your ISP technical people what they recommend. I
doubt that anyone here has ever seen an arrangement like that.
