Hi All I've been trying to configure a router/firewall with 5 zones (2 of which are ISP links) unsuccessfully. So far I've managed to patch the kernel with the ROUTE target, and I've got rules as follows: FORWARD chain filter table: ACCEPT 0 -- ethxx0 eth4 10.0.0.0/24 0.0.0.0/0 ACCEPT 0 -- eth4 ethxx0 0.0.0.0/0 10.0.0.0/24 FORWARD chain mangle table: ROUTE tcp -- * * 10.0.0.67 !192.168.1.0/24 tcp dpts:80:90 ROUTE oif:eth4 continue POSTROUTING chain nat table: SNAT 0 -- * eth4 0.0.0.0/0 0.0.0.0/0 to:10.1.0.2 ethxx0 is my internal LAN eth4 is my 2nd ISP connection 10.0.0.67 is my workstation 10.1.0.2 is the ip bound to eth4 The other ISP link is working, we host around 12 websites on servers in our DMZ, we have outgoing web browsing, email, MSN, etc. using various nat rules for that interface, they all work. I can see using tcpdump that the packets are leaving my workstation, being mangles to change the route, going out the 2nd ISP link, coming back into the 2nd ISP link, but then they disappear. My forwarding rules as shown above do not show any traffic. This has me stumped. As I've stated, I have nat (both SNAT and DNAT) working on the other ISP interface on the same machine. Where should I start looking? Regards Ray -- Raymond Leach RCHQ Hobbies (http://www.rchq.co.za/) (T)+27-82-575-6975 (F)+27-86-652-2773
