I've recently added a server (2003) to my home network. It has 2 LAN adaptors. 1 is connected directly to my router (RTA1320) and is receiving an IP via DHCP from the router (192.168.1.1 router default). The 2nd NIC is a plugin type, configured manually to 192.168.0.1 as a byproduct of setting up the ICS. the .0.1 NIC is in turn plugged into an 8 port 10/100 N-way switch, where all my other computers are connected. AD is turned on for the server all connections are functioning as they should and all computers can access the web through the server. BUT...... my port forwarding rules no longer work. When i had my #1 computer connected directly to the router (via switch) I could configure a forwarding rule and have it function. But since the implementation of the server, I can no longer control the opening of specific ports. The firewall on the router is not activated, NAT is turned on for the ICS connection(server side). I have been beating my head against this wall for a while now, to no avail. I'm out of ideas to try next. Any input from those much smarter than myself would be greatly appreciated :D

Have you actually set any port forwarding in ICS at all?

The only port forwarding I know how to setup is within the router. What steps do I take to set rules in the ICS? I've been looking through all I can think of, and cant find anything towards that end.

Can I ask why you have the internet connection going through the server using ICS rather then just pluging the router directly into the switch and having the server connect to the swtich as well?

I set the server up as a central point of the network so I was able to run network monitoring software to try and find out where all our bandwidth is going :) Don't know enough about servers to know if I've done it the easy/right way, but it was the only thing I could think of at the time. Am I able to have a server connected to the switch as you suggest and still have it monitor all incoming/outgoing traffic?

You should be able to use something like this

http://ipaudit.sourceforge.net/

I have just found that one so not sure if it is any good. There may well be better ones out there but in short yes there are applications that will tell you what data is being used on your network without having to have all the data go though your server.

righto, the situation sofar. IPaudit is uncompiled and I cant be bothered mucking about with another new piece of software right now lol. <----sidelined idea. I have disabled the Routing and remote access role from AD and have swapped to regular ole ICS. I have even go sofar as to set a static route from my router > server > end network. details are as follows. router(192.168.1.1) > serverNIC1(192.168.1.2 DHCP'd) > serverNIC2 (192.168.0.1ICS set) > myPC(192.168.0.12 DHCP'd). Port forwarding rule that used to work prior to server install still present but still non-functional. Sorry if I'm a trying person, but even though I have tried, I am unable to work out how to set port forwarding rules into the ICS of the server. All home PC's on the serverNIC2 network can all access the internet via browsers, but I am still receiving a Listen Error within Utorrent client for example. Forwarding rules just still arent working. /sigh :) thanks for any info or advice

You will have to port forward from the router to the ICS server ip address then from the ICS server to the PC. This is because you now have two layers of NAT (net address translation).

Thanks Ragnor, I'll give that a shot. Still not entirely sure how to set port forwarding within ICS, but I'll attempt to mull it out :)
