Default Port Forwarding

Hi Slackware Community,

I have an problem with my little Home Network wich looks like this :

I have an old Laptop (DX66) as my router/Firewall and an Pentium200 as
my Web/FTP server.
My firewall is the gShield script wich is btw. superb imho.

Now this firewall has the option to do Port Forwarding wich i configged
also in the config file.
Forward mydns:21 -> 192.168.0.6:21
(The Router hasn't an FTP running.
If i try to connect from the outside on this FTP the connection is being
refused. (Not if i OPEN the Port instead of Forwarding.)

I asked an friend who uses OpenBSD as OS and said he has an NATD Daemon
running.
Do i need also an NATD Daemon to run on my Fresh Slackware 9.1 Installment ?

Any help appreciated and Thank you in advance

Regards, hanfsome.

No, you don't. NAT comes with iptables:

Can't help you with gShield though, I don't know it.

OBSD does NAT as part of the firewall. The only time you need to run
anything else is if you are running VoIP or to support active FTP.

Ok, all Problems are solved.
The Problem i could not ping to the world was caused by an incorrect gateway
setting.

Again thanks !
