How enable port forwarding to NIC on internal network

[jfinighan]

I am running SBS 2000, 2 NICs, one external, one on internal network. I am running a service on a server on the internal network which opens port 23053 on 192.168.0.111. How do I port forward this so that I can see that port on the external interface of the SBS machine?

Set up NAT on your server.

CoolClark, Can you help with the details?

Check out this article.

Network Address Translation (NAT) is installed/configured through RRAS. Don't use ICS. It's easier to setup and use but you lose functionality.

Once NAT is installed and working properly. Goto the RRAS MMC. Dbl-clk your server. Dbl-clk IP Routng. Dbl-clk NAT. In the right hand window dbl-clk your internet connection. select special ports. This is where you set up your port translation.

Just shout if you get stuck.

Thanks CoolClark, I have had a go, but no success yet. I'm not sure if I have communicated my problem well - it is clients trying to get in from outside that I need to give access to. I have remote sites that need to come in through the permenant internet connection on the SBS server, that need to see the special port that is currently available on the internal network. So it looks like this:

SBS server FileShare server
WAN NIC LAN NIC NIC
210.13.213.38 192.168.0.110 192.168.0.111

On internal network can see port 23053 on 192.168.0.111.

External clients need to see 23053 on 210.13.213.38.

If NAT can do this, what do I set as the public port number when setting up the special port?

I had another tech say to me that I should be doing all this under Publishing in ISA server - is that off the track?

Thanks again for the help.

on the public port number you type 23053 too. The public port is the port that seem by external client.
NAT is a simply product than ISA server. Hope this can help.

You don't need ISA server to do what you are trying to do.
ISA can do it, but is a far expensive and complex solution, and will probably introduce other problems.

You can do it using ICS on SBS using free third party software such as:

The procedure you are reffering to is also known as port tunneling - and is commonly used to provide services from a specific machine that is on a private network.

Hope this helps, I found it simpler than trying to configure NAT.
