RE: Port Forwarding With 2 NIC Configuration

Tech-Archive recommends: Fix windows errors by optimizing your registry

Dear Rolf:
Thank you for your kind reply! :)

To answer your questions:
1. Yes, we need to define the port which you want to forward through RRAS,
we also need to make sure whether it uses TCP or UDP.

2. Yes, you can do this without any difficulties. Here, I provide the steps
as following:

a. Click Start->Run, type "rrasmgmt.msc" (without quotation mark).

b. Navigate to Servername\IP Routing\NAT /Basic Firewall. On the right
pane, double click Network connection.

c. Switch to Address Pool, click Add and type the range of your public IPs,
then click OK.

d. Click Reservations, and then click Add, type the internal IP which is
mapped to the private IP. Don't forget to check the checkbox "Allow
incoming sessions to this address" if you want this internal compuer
accessible.

e. Click OK and Apply the configuration.

By the way, if you have a router at the SBS end, the router will do a
1-to-1to-1 NAT, which means internal IP-to-external IP of SBS-to-public IP.
It will fuction perfectly like a charm.

Hope the clarification address your concern, please feel free to let me
know if you have any concerns or questions.

Enjoy you weekend, Rolf! :)

| Thanks so much! That very much helps. I only have 2 remaining questions:
|
| 1) Am I required to enter a protocol? I am only interested in doing
| straight port forwarding (I am comparing to when I do it via a router,
which
| does not require a protocol to be specified).
|
| 2) Can SBS do 1-to-1 Natting? I have a couple public IPs which must be
| mapped directly to a couple internal IPs. Again, I am only familiar with
| doing this via a router (and this option is not available to me at this
| point).
|
| Thanks again so VERY VERY much for your patience with me!!!
|
