Hi,
can anyone help?

I'm not a Linux person but very OK with computers, I have just setup Smoothwall 3-NIC cards and I can't seem to get the machine on the orange network (DMZ) to be seen from the outside.


External IP from cable modem is
80.192.xxx.x / 255.255.255.0 eth2

Internal IP range is

10.10.0.1-20 / 255.255.255.0 eth0

DMZ network is

192.168.0.2-255 / 255.255.255 eth1

The machine on the DMZ has a fixed ip of 192.168.0.2 I set the DNS's manually but it can't see internet and internet cant see it (via a game server)

I can ping it from the green network but can't ping back (should hope not).

Is there something I'm missing?

Thanks

there is a network address translation and or port forwarding problem going on.

ok..
1. Search google for how port forwarding works
2. You will need to forward all game server traffic (port number)from your provider to the quake server.
3. can you ping the internet from the green zone? if so NAT is working fine.
4. if NAT is working is the game server firewall restricting traffic coming in and out? it should only be the games port number
4. make sure you can ping the net from the game server

am i making sense? how the gateway/firewall is pushing all the appropriate port number(game traffic) to the actual game server. So it seems like that the gamers are actually connecting to the smoothwall, in fact they really connecting to your internal putah.

The title says it all, I understand about port fowarding but as the machine is in the DMZ why does it need PF?

I thought all it's porst where accessable vie the outside, if not whats the point of a DMZ?

Thanks

The smoothwall will be doing enough for you so that you wont need to have a PF in place on the DMZ machine.

all ports wont be accessible from the outside as you will only want to forward the game server traffic. Do you want all server requests to be forwarded to the DMZ machine?

why would you want to leave all ports open to the outside? and then go and leave all ports open on the DMZ machine?

I only want the game server to work, I'm happy to keep as many ports closed as possible.

So you think it the lack of port fowarding thats causing the problem do you?
