Hello!

I need help with configuring my firewall with Firewall Builder software. I have Fedora Core 1 and iptables 1.2.8.

My LAN are two computer connected. One is a desktop machine, the second is a server.

I have NAT rule that shares the internet to my desktop.

I would like to forward a port for example 80 from my server (linux) to the workstation, that will provide access to my webserver on my workstation.

Need a NAT rule made in FWBuilder, because I have my whole firewall configuration in it ;-)

Any one has any links that would help me?
By the way, I've tried to do this, but I have cuted access to my server.

Oh, and maybe any one knows what is the best software to help me view my iptables access logs (in a better, for example graphically way).

Don't know the specifics of how to do it with FWBuilder, but the rule itself would be:

iptables -t nat -A PREROUTING -i ethX -p tcp --dport 80 -j DNAT --to-destination 123.456.78.9

where ethX is the external interface connected to the internet and 123.456.78.9 is the IP addres of the desktop. Depending on how you have your firewall configured, you may need to add a rule to forward as well:

iptables -A FORWARD -i ethX -o ethY -p tcp --dport 80 -j ACCEPT

Where ethY is the internal interface connected to the desktop.

Oh, and maybe any one knows what is the best software to help me view my iptables access logs (in a better, for example graphically way).
Maybe Webmin setup to listen on the internal IP, fwlogview, or fireparse?

I've made the rules in fwbuilder by myself ...

Anyway thx, for help especially with the logview software ;-P
