Does anyone feel like giving a somewhat detailed explanation of the differences in loading the ip_tables modules versus building it into the kernel? I've got several RedHat Linux firewalls and when it comes to upgrading the kernels, loading ip_tables as modules is easy. Otherwise, I have to upgrade my kernel and then go back and re-compile ip_tables into the kernel. This has proven to be much more time consuming, especially with the growth of ip_tables use on our network. Thoughts? Thanks in advance? Khanh Tran Network Operations Sarah Lawrence College
