I need to use Novell security manager (powered by astro linux) as my firewall gateway system. I installed the system. Now i have some problems in Packet filtering rules.
In Novell security manager all the packets are blocked by default. I need to connect from internal node to internet using the firewall system.Please help me to set essential rules to connect from internal network to external network.

My network interface defenition is given below:

internal- Address : 192.168.40.2,Network : 192.168.40.0/24,broadcast : 192.168.40..255
external - Address:10.11.8.11,network:10.11.8.0/28,broadcast:10.11.8.15

external gateway is 10.11.8.9

Now i can ping internal and external network from gateway system. But i cant connect any external network from internal nodes.

Thank you,

1. you need to know what you want to connect to.
2. you need to know what your firewall is doing now. (why is it blocking it)

if your trying to connect to an external web page then you need to allow forwarding of port 80, that can be done several different ways. If your trying to connect to remote file/printer shareing or nfs its probably a default rule dropping it.

to get an idea of what your firewall is doing now you should get a list.
/usr/sbin/iptables -L

when you try to connect to something what log messages are you getting? what is it blocking?
tail -f /var/log/firewall
