SUSE 10.2

Hello,

I'm a Linux newbie crossing over from the Windows world. I just set up a server with SUSE Linux 10.2, SQUID 2.6? (the newest), and DansGuardian for filtering. I'm trying to setup a second NIC for use with the DHCP Server which I've installed under YaST. The second NIC connects to a wireless AP which will assign IPs to various laptops which must be filtered. The laptops are getting an IP address, and can browse the web if I turn on 'masquerading' at the SUSE firewall. However, they are not filtered. I would like all web requests to forward to port 8080 of Dansguardian, but don't know how. I figured it should be in the 'masquerading' section of the SUSE firewall, but I can't get it to work. If I put in 10.0.0.150 - port 8080 under the proxy settings on the client, then browsing is filtered. So, everything is in place, but I don't want to enter the proxy settings and still have it filtered. In other words, all requests should forward to 8080.

Here is my current setup:

NIC #1 (eth0)(external zone on Firewall):
IP: 10.0.0.150
Gateway - 10.0.0.1 (my router)

NIC #2 (eth1)(internal zone on Firewall):
IP: 10.10.0.1
Gateway: 10.0.0.1

Thanks for any help....

Guess the Linux Gurus are all over at Yahoo Answers...

Answer:
1. Edit the configuration file for SUSE Firewall at: /etc/sysconfig/SuSEfirewall2

2. Around Section 15, here's what I entered:

FW_REDIRECT_TCP="10.10.0.0/24,0/0,80,8080"

This allows any client making a port 80 request in the 10.10.0.x range to be automatically forwarded to port 8080 and be filtered.
