繁忙桌上的iptables

Question

I have busybox installed as a 'starter' package on my embedded linux board and I also need to use iptables to configure some firewall rules.

Is there a way to get access to iptables from the busybox shell?

Otherwise, how can I exit busybox shell to get to the iptables command?

Thank you.

Answer 1

（1）First you need to how to modify the kernel， install modules and applications in Busybox environment.

（2）Then you can config the kernel to support Iptables (most in menu of network/netfilter),you can build those kernel modules as ko modules or part of kernel image.

（3）go to homepage to netfilter to get application souce code. Build and install.

（4）modprobe the ko (for example)

modprobe iptable_filter
modprobe ip_tables

（5）try your IPTABLES....If meet problem, you may goto step 2 to make some change.
