recently I have upgraded the kernel from 2.4.20-20.8 to 2.4.22 by using back my old kernel config.
I am now try to learn setup firewall on my local LAN using the new kernel.Is there an easier way to compile the kernel for the firewall option enabled in the new kernel without going through the "make config" answering the Q&A ?
I tried browse to the directory /2.4.22 and pico .config but I was not able to get the option CONFIG_FIREWALL in the config file.Shouldn't that this option should be available since the my last kernel version is 2.4.20-20.8?Most of the option which required for setting up the firewall is not available as well..
thank you for answering this cause this is the first time I try to setup a firewall in linux
If I egrep /usr/src/linux/.config -ie "(netfil|iptab)" I get all the Netfilter and iptables entries, but no "CONFIG_FIREWALL".
Are these kernels provided by your distribution (patched kernel), or are they kernel.org kernels (clean)?
I just did a futher research and seems like CONFIG_NETFILTER had replace CONFIG_FIREWALL in kernel 2.4.x , am I right ?
any suggestion tutorial I may refer to to setup the firewall from scratch ( more details tutorial will be preferable coz I am new in this firewall setup )...
